Question

A car travel 100 km with a speed of 50 km/hr and next 100 km with a speed of 40 km/hr.Find the total time of journey.

Answer 1

Answer:

Explanation:

distance travelled at the speed of 50 kmph = 100 km

distance travelled at the speed of 40 kmph = 100 km

time taken to travel 100 km at the speed of 50 kmph = 2 hours

time taken to travel 100 km at the speed of 40 kmph = 100/40 = 5/2 hours = 2 hours 30 min

total time = 4 hours 30 min
