A car travels 71 km in 39 minutes. At the same rate, how many km will it travel in one hour

Answer:_______________

A car travels 70 km in 35 minutes. At the same rate, how many km will it travel in one hour

Answer: 120 km

SOLUTION 1 :

Given :

Distance travelled (km)	Time taken (min)
70	35 (x)
(a)	60 (y)

As time taken increases, distance travelled also increases.

It is in direct variation.

So, $\frac{x}{y}$ = Constant

$\frac{35}{60}$ = $\frac{70}{a}$

a= $\frac{(70x60)}{35}$

= $\frac{4200}{35}$

= 120 km

A car travels 77 km in 42 minutes. At the same rate, how many km will it travel in one hour

Answer: 110 km

SOLUTION 1 :

Given :

Distance travelled (km)	Time taken (min)
77	42 (x)
(a)	60 (y)

As time taken increases, distance travelled also increases.

It is in direct variation.

So, $\frac{x}{y}$ = Constant

$\frac{42}{60}$ = $\frac{77}{a}$

a= $\frac{(77x60)}{42}$

= $\frac{4620}{42}$

= 110 km

A car travels 64 km in 37 minutes. At the same rate, how many km will it travel in one hour

Answer: 104 km

SOLUTION 1 :

Given :

Distance travelled (km)	Time taken (min)
64	37 (x)
(a)	60 (y)

As time taken increases, distance travelled also increases.

It is in direct variation.

So, $\frac{x}{y}$ = Constant

$\frac{37}{60}$ = $\frac{64}{a}$

a= $\frac{(64x60)}{37}$

= $\frac{3840}{37}$

= 104 km

A car travels 69 km in 44 minutes. At the same rate, how many km will it travel in one hour

Answer: 94 km

SOLUTION 1 :

Given :

Distance travelled (km)	Time taken (min)
69	44 (x)
(a)	60 (y)

As time taken increases, distance travelled also increases.

It is in direct variation.

So, $\frac{x}{y}$ = Constant

$\frac{44}{60}$ = $\frac{69}{a}$

a= $\frac{(69x60)}{44}$

= $\frac{4140}{44}$

= 94 km

A car travels 73 km in 36 minutes. At the same rate, how many km will it travel in one hour

Answer: 122 km

SOLUTION 1 :

Given :

Distance travelled (km)	Time taken (min)
73	36 (x)
(a)	60 (y)

As time taken increases, distance travelled also increases.

It is in direct variation.

So, $\frac{x}{y}$ = Constant

$\frac{36}{60}$ = $\frac{73}{a}$

a= $\frac{(73x60)}{36}$

= $\frac{4380}{36}$

= 122 km

A car travels 75 km in 43 minutes. At the same rate, how many km will it travel in one hour

Answer: 105 km

SOLUTION 1 :

Given :

Distance travelled (km)	Time taken (min)
75	43 (x)
(a)	60 (y)

As time taken increases, distance travelled also increases.

It is in direct variation.

So, $\frac{x}{y}$ = Constant

$\frac{43}{60}$ = $\frac{75}{a}$

a= $\frac{(75x60)}{43}$

= $\frac{4500}{43}$

= 105 km

A car travels 60 km in 36 minutes. At the same rate, how many km will it travel in one hour

Answer: 100 km

SOLUTION 1 :

Given :

Distance travelled (km)	Time taken (min)
60	36 (x)
(a)	60 (y)

As time taken increases, distance travelled also increases.

It is in direct variation.

So, $\frac{x}{y}$ = Constant

$\frac{36}{60}$ = $\frac{60}{a}$

a= $\frac{(60x60)}{36}$

= $\frac{3600}{36}$

= 100 km

A car travels 71 km in 43 minutes. At the same rate, how many km will it travel in one hour

Answer: 99 km

SOLUTION 1 :

Given :

Distance travelled (km)	Time taken (min)
71	43 (x)
(a)	60 (y)

As time taken increases, distance travelled also increases.

It is in direct variation.

So, $\frac{x}{y}$ = Constant

$\frac{43}{60}$ = $\frac{71}{a}$

a= $\frac{(71x60)}{43}$

= $\frac{4260}{43}$

= 99 km

A car travels 74 km in 44 minutes. At the same rate, how many km will it travel in one hour

Answer: 101 km

SOLUTION 1 :

Given :

Distance travelled (km)	Time taken (min)
74	44 (x)
(a)	60 (y)

As time taken increases, distance travelled also increases.

It is in direct variation.

So, $\frac{x}{y}$ = Constant

$\frac{44}{60}$ = $\frac{74}{a}$

a= $\frac{(74x60)}{44}$

= $\frac{4440}{44}$

= 101 km

10)

A car travels 71 km in 39 minutes. At the same rate, how many km will it travel in one hour

Answer: 109 km

SOLUTION 1 :

Given :

Distance travelled (km)	Time taken (min)
71	39 (x)
(a)	60 (y)

As time taken increases, distance travelled also increases.

It is in direct variation.

So, $\frac{x}{y}$ = Constant

$\frac{39}{60}$ = $\frac{71}{a}$

a= $\frac{(71x60)}{39}$

= $\frac{4260}{39}$

= 109 km
