Question

By travelling at a speed of $48$ kilometres per hour, a car can finish a certain journey in $10$ hours. To cover the same distance in $8$ hours, the speed of the car should be

• A. $60$ km/h
• B. $80$ km/h
• C. $30$ km/h
• D. $40$ km/h

Answer 1

The correct option is A

$60$ km/h

Given that ,

Speed of car = $48$ km/hr

Time taken = $10$ hr

As we know,

Distance = speed $\times$ time

Distance = $48\times 10$

Distance = $480$km

Speed required by car to cover $480$ km in $8$ hours $=\frac{480}{8}$

Hence, Speed required by car to cover $480$ km in $8$ hours $60$ km/hr .
