A car has to cover a distance of 200 km in 8 hours. If it covers half of the distance in (3/4th) of the time. What should be its speed to cover the remaining distance? A. Speed required to cover 650 km in 13 h B. Speed required to cover 750 km in 30 h C. 50 D. 15 Correct Answer A and C

Given:

Distance covered by car in 8 hours = 200 km

Calculation:

First half of the distance = 100 km

Time taken to cover first 100 km = (3/4) × 8 = 6 h

Second half of the distance = 100 km

Time taken to cover second half = 8 – 6 = 2 h

Speed of the car while covering second half of the distance = 100/2 = 50 km/h

A. Speed required to cover 650 km in 13 h

Speed = 650/13 = 50 km/h

A is correct.

C. 50

C is correct.

∴ A and C is correct.
