Question

A car travelling at a speed of 40 km/ hour can complete a journey in 9 hours. How long will it take to travel the same distance at 60 km/hour?.

• A. 6 hours
• B. 3 hours
• C. 4 hours
• D. $4\frac{1}{4}hours$

Answer 1

The correct option is A 6 hours

$Distance=Speed\times Time$

When speed is 40 kmph

Distance traveled by car $=40\times 9$

$=360km$

When speed is 60 kmph

Time taken to complete the journey $=\frac{360}{60}$

$=6hours$
