Question

How much more distance is covered by car than truck in 3 hours , if truck moves with a speed of 19 km per hour and car moves with a speed of 23 km per hour?

• A. 11 km
• B. 10 km
• C. 12 km
• D. 14 km

Answer 1

The correct option is C 12 km

Distance covered by car in one hour
= 23 km

Distance covered by car in 3 hour
= 23 $\times$ 3
= 69

Distance covered by truck in one hour
= 19 km

Distance covered by truck in 3 hour
= 19 $\times$ 3
= 57
Difference in distance covered
= 69km - 57km
= 12km
