A car travels 74 km in 39 minutes. At the same rate, how many km will it travel in one hour

Answer:_______________

A car travels 62 km in 39 minutes. At the same rate, how many km will it travel in one hour

Answer: 95 km

SOLUTION 1 :

Given :

Distance travelled (km)	Time taken (min)
62	39 (x)
(a)	60 (y)

As time taken increases, distance travelled also increases.

It is in direct variation.

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

$\frac{39}{60}$ = $\frac{62}{a}$

a= $\frac{(62x60)}{39}$

= $\frac{3720}{39}$

= 95 km

A car travels 77 km in 45 minutes. At the same rate, how many km will it travel in one hour

Answer: 103 km

SOLUTION 1 :

Given :

Distance travelled (km)	Time taken (min)
77	45 (x)
(a)	60 (y)

As time taken increases, distance travelled also increases.

It is in direct variation.

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

$\frac{45}{60}$ = $\frac{77}{a}$

a= $\frac{(77x60)}{45}$

= $\frac{4620}{45}$

= 103 km

A car travels 68 km in 38 minutes. At the same rate, how many km will it travel in one hour

Answer: 107 km

SOLUTION 1 :

Given :

Distance travelled (km)	Time taken (min)
68	38 (x)
(a)	60 (y)

As time taken increases, distance travelled also increases.

It is in direct variation.

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

$\frac{38}{60}$ = $\frac{68}{a}$

a= $\frac{(68x60)}{38}$

= $\frac{4080}{38}$

= 107 km

A car travels 71 km in 40 minutes. At the same rate, how many km will it travel in one hour

Answer: 107 km

SOLUTION 1 :

Given :

Distance travelled (km)	Time taken (min)
71	40 (x)
(a)	60 (y)

As time taken increases, distance travelled also increases.

It is in direct variation.

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

$\frac{40}{60}$ = $\frac{71}{a}$

a= $\frac{(71x60)}{40}$

= $\frac{4260}{40}$

= 107 km

A car travels 64 km in 39 minutes. At the same rate, how many km will it travel in one hour

Answer: 98 km

SOLUTION 1 :

Given :

Distance travelled (km)	Time taken (min)
64	39 (x)
(a)	60 (y)

As time taken increases, distance travelled also increases.

It is in direct variation.

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

$\frac{39}{60}$ = $\frac{64}{a}$

a= $\frac{(64x60)}{39}$

= $\frac{3840}{39}$

= 98 km

A car travels 71 km in 37 minutes. At the same rate, how many km will it travel in one hour

Answer: 115 km

SOLUTION 1 :

Given :

Distance travelled (km)	Time taken (min)
71	37 (x)
(a)	60 (y)

As time taken increases, distance travelled also increases.

It is in direct variation.

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

$\frac{37}{60}$ = $\frac{71}{a}$

a= $\frac{(71x60)}{37}$

= $\frac{4260}{37}$

= 115 km

A car travels 71 km in 44 minutes. At the same rate, how many km will it travel in one hour

Answer: 97 km

SOLUTION 1 :

Given :

Distance travelled (km)	Time taken (min)
71	44 (x)
(a)	60 (y)

As time taken increases, distance travelled also increases.

It is in direct variation.

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

$\frac{44}{60}$ = $\frac{71}{a}$

a= $\frac{(71x60)}{44}$

= $\frac{4260}{44}$

= 97 km

A car travels 74 km in 38 minutes. At the same rate, how many km will it travel in one hour

Answer: 117 km

SOLUTION 1 :

Given :

Distance travelled (km)	Time taken (min)
74	38 (x)
(a)	60 (y)

As time taken increases, distance travelled also increases.

It is in direct variation.

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

$\frac{38}{60}$ = $\frac{74}{a}$

a= $\frac{(74x60)}{38}$

= $\frac{4440}{38}$

= 117 km

A car travels 73 km in 37 minutes. At the same rate, how many km will it travel in one hour

Answer: 118 km

SOLUTION 1 :

Given :

Distance travelled (km)	Time taken (min)
73	37 (x)
(a)	60 (y)

As time taken increases, distance travelled also increases.

It is in direct variation.

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

$\frac{37}{60}$ = $\frac{73}{a}$

a= $\frac{(73x60)}{37}$

= $\frac{4380}{37}$

= 118 km

10)

A car travels 74 km in 39 minutes. At the same rate, how many km will it travel in one hour

Answer: 114 km

SOLUTION 1 :

Given :

Distance travelled (km)	Time taken (min)
74	39 (x)
(a)	60 (y)

As time taken increases, distance travelled also increases.

It is in direct variation.

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

$\frac{39}{60}$ = $\frac{74}{a}$

a= $\frac{(74x60)}{39}$

= $\frac{4440}{39}$

= 114 km
