<u>Answer: </u>

The car’s rate in kilometer per minute is 1.2 kilometer/minute and in 20 min it can travel 24 kilometer

<u>Solution: </u>

It is given that it can travel 72 kilometer per hour.

We know 1 hour = 60 min

So, the car travels in

60 min = 72 hour

$1 \min =\frac{72}{60} \text { hours or } \frac{6}{5} \text { hours or } 1_{5}^{1} \text { hours. }$

Thus the cars rate in kilometer per minute is $\frac{6}{5}$ is 1.2 kilometer per minute.

Now we know in 1 minute the car can travel 1.2 kilometer.

Therefore in 20 minutes it will travel 1.2 $\times$ 20 kilometers= 24 kilometers
