Ram needs to reach the examination center in 6 hours, the journey itself is 250 km. If Ram has covered (3/5)th of the distance in 3.5 hours, then what is the speed required to reach the destination 30 minutes earlier than the required time?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 50 km/h.
Distance already covered = (3/5) × 250 = 150 km
Remaining distance = 250 - 150 = 100 km
Target time = 6 - 0.5 = 5.5 hours
Time already spent = 3.5 hours
Remaining time = 5.5 - 3.5 = 2 hours
Required speed = 100/2 = 50 km/hr
