A car travels 68 km in 44 minutes. At the same rate, how many km will it travel in one hour

Answer:_______________

A car travels 72 km in 35 minutes. At the same rate, how many km will it travel in one hour

Answer: 123 km

SOLUTION 1 :

Given :

Distance travelled (km)	Time taken (min)
72	35 (x)
(a)	60 (y)

As time taken increases, distance travelled also increases.

It is in direct variation.

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

$\frac{35}{60}$ = $\frac{72}{a}$

a= $\frac{(72x60)}{35}$

= $\frac{4320}{35}$

= 123 km

A car travels 62 km in 42 minutes. At the same rate, how many km will it travel in one hour

Answer: 89 km

SOLUTION 1 :

Given :

Distance travelled (km)	Time taken (min)
62	42 (x)
(a)	60 (y)

As time taken increases, distance travelled also increases.

It is in direct variation.

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

$\frac{42}{60}$ = $\frac{62}{a}$

a= $\frac{(62x60)}{42}$

= $\frac{3720}{42}$

= 89 km

A car travels 69 km in 38 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)
69	38 (x)
(a)	60 (y)

As time taken increases, distance travelled also increases.

It is in direct variation.

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

$\frac{38}{60}$ = $\frac{69}{a}$

a= $\frac{(69x60)}{38}$

= $\frac{4140}{38}$

= 109 km

A car travels 66 km in 37 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)
66	37 (x)
(a)	60 (y)

As time taken increases, distance travelled also increases.

It is in direct variation.

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

$\frac{37}{60}$ = $\frac{66}{a}$

a= $\frac{(66x60)}{37}$

= $\frac{3960}{37}$

= 107 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 79 km in 44 minutes. At the same rate, how many km will it travel in one hour

Answer: 108 km

SOLUTION 1 :

Given :

Distance travelled (km)	Time taken (min)
79	44 (x)
(a)	60 (y)

As time taken increases, distance travelled also increases.

It is in direct variation.

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

$\frac{44}{60}$ = $\frac{79}{a}$

a= $\frac{(79x60)}{44}$

= $\frac{4740}{44}$

= 108 km

A car travels 63 km in 43 minutes. At the same rate, how many km will it travel in one hour

Answer: 88 km

SOLUTION 1 :

Given :

Distance travelled (km)	Time taken (min)
63	43 (x)
(a)	60 (y)

As time taken increases, distance travelled also increases.

It is in direct variation.

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

$\frac{43}{60}$ = $\frac{63}{a}$

a= $\frac{(63x60)}{43}$

= $\frac{3780}{43}$

= 88 km

A car travels 69 km in 45 minutes. At the same rate, how many km will it travel in one hour

Answer: 92 km

SOLUTION 1 :

Given :

Distance travelled (km)	Time taken (min)
69	45 (x)
(a)	60 (y)

As time taken increases, distance travelled also increases.

It is in direct variation.

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

$\frac{45}{60}$ = $\frac{69}{a}$

a= $\frac{(69x60)}{45}$

= $\frac{4140}{45}$

= 92 km

A car travels 71 km in 35 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)
71	35 (x)
(a)	60 (y)

As time taken increases, distance travelled also increases.

It is in direct variation.

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

$\frac{35}{60}$ = $\frac{71}{a}$

a= $\frac{(71x60)}{35}$

= $\frac{4260}{35}$

= 122 km

10)

A car travels 68 km in 44 minutes. At the same rate, how many km will it travel in one hour

Answer: 93 km

SOLUTION 1 :

Given :

Distance travelled (km)	Time taken (min)
68	44 (x)
(a)	60 (y)

As time taken increases, distance travelled also increases.

It is in direct variation.

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

$\frac{44}{60}$ = $\frac{68}{a}$

a= $\frac{(68x60)}{44}$

= $\frac{4080}{44}$

= 93 km
