Answer:
The car’s rate in kilometer per minute is 1.2 kilometer/minute and in 20 min it can travel 24 kilometer
Solution:
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
[tex]1 \min =\frac{72}{60} \text { hours or } \frac{6}{5} \text { hours or } 1_{5}^{1} \text { hours. }[/tex]
Thus the cars rate in kilometer per minute is [tex]\frac{6}{5}[/tex] 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 [tex]\times[/tex] 20 kilometers= 24 kilometers
