A car travels 63 km in 40 minutes. At the same rate, how many km will it travel in one hour

Answer:_______________

A car travels 80 km in 38 minutes. At the same rate, how many km will it travel in one hour

Answer: 126 km

SOLUTION 1 :

Given :

Distance travelled (km)	Time taken (min)
80	38 (x)
(a)	60 (y)

As time taken increases, distance travelled also increases.

It is in direct variation.

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

$\frac{38}{60}$ = $\frac{80}{a}$

a= $\frac{(80x60)}{38}$

= $\frac{4800}{38}$

= 126 km

A car travels 79 km in 40 minutes. At the same rate, how many km will it travel in one hour

Answer: 119 km

SOLUTION 1 :

Given :

Distance travelled (km)	Time taken (min)
79	40 (x)
(a)	60 (y)

As time taken increases, distance travelled also increases.

It is in direct variation.

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

$\frac{40}{60}$ = $\frac{79}{a}$

a= $\frac{(79x60)}{40}$

= $\frac{4740}{40}$

= 119 km

A car travels 63 km in 36 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)
63	36 (x)
(a)	60 (y)

As time taken increases, distance travelled also increases.

It is in direct variation.

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

$\frac{36}{60}$ = $\frac{63}{a}$

a= $\frac{(63x60)}{36}$

= $\frac{3780}{36}$

= 105 km

A car travels 68 km in 40 minutes. At the same rate, how many km will it travel in one hour

Answer: 102 km

SOLUTION 1 :

Given :

Distance travelled (km)	Time taken (min)
68	40 (x)
(a)	60 (y)

As time taken increases, distance travelled also increases.

It is in direct variation.

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

$\frac{40}{60}$ = $\frac{68}{a}$

a= $\frac{(68x60)}{40}$

= $\frac{4080}{40}$

= 102 km

A car travels 66 km in 44 minutes. At the same rate, how many km will it travel in one hour

Answer: 90 km

SOLUTION 1 :

Given :

Distance travelled (km)	Time taken (min)
66	44 (x)
(a)	60 (y)

As time taken increases, distance travelled also increases.

It is in direct variation.

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

$\frac{44}{60}$ = $\frac{66}{a}$

a= $\frac{(66x60)}{44}$

= $\frac{3960}{44}$

= 90 km

A car travels 70 km in 45 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)
70	45 (x)
(a)	60 (y)

As time taken increases, distance travelled also increases.

It is in direct variation.

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

$\frac{45}{60}$ = $\frac{70}{a}$

a= $\frac{(70x60)}{45}$

= $\frac{4200}{45}$

= 93 km

A car travels 60 km in 45 minutes. At the same rate, how many km will it travel in one hour

Answer: 80 km

SOLUTION 1 :

Given :

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

As time taken increases, distance travelled also increases.

It is in direct variation.

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

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

a= $\frac{(60x60)}{45}$

= $\frac{3600}{45}$

= 80 km

A car travels 64 km in 40 minutes. At the same rate, how many km will it travel in one hour

Answer: 96 km

SOLUTION 1 :

Given :

Distance travelled (km)	Time taken (min)
64	40 (x)
(a)	60 (y)

As time taken increases, distance travelled also increases.

It is in direct variation.

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

$\frac{40}{60}$ = $\frac{64}{a}$

a= $\frac{(64x60)}{40}$

= $\frac{3840}{40}$

= 96 km

A car travels 80 km in 37 minutes. At the same rate, how many km will it travel in one hour

Answer: 130 km

SOLUTION 1 :

Given :

Distance travelled (km)	Time taken (min)
80	37 (x)
(a)	60 (y)

As time taken increases, distance travelled also increases.

It is in direct variation.

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

$\frac{37}{60}$ = $\frac{80}{a}$

a= $\frac{(80x60)}{37}$

= $\frac{4800}{37}$

= 130 km

10)

A car travels 63 km in 40 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)
63	40 (x)
(a)	60 (y)

As time taken increases, distance travelled also increases.

It is in direct variation.

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

$\frac{40}{60}$ = $\frac{63}{a}$

a= $\frac{(63x60)}{40}$

= $\frac{3780}{40}$

= 95 km
