Question

Akhil is running a marathon. He covered a distance of 15 km in 2 hours at a constant speed. Find the distance he would cover in the next 3 hours if he runs at the same speed.

• A. 10 km
• B. 2.5 km
• C. 37.5 km
• D. 22.5 km

Answer 1

The correct option is D 22.5 km

In 2 hours, Akhil covered a distance of 15 km.

Distance covered in 1 hour = $\frac{15}{2}$
= 7.5 km

∴ Distance covered in 3 hours = 7.5 × 3
= 22.5 km
