Question

A motor Car does journey in 10 hrs. The first half at 21km per hour and rest at 23.8 km per hour.Find the distance

distance = speed*time

the journey is 10 hours long so the first half is 5 hours and the second half is 5 hours

distance for the first half = speed*5, where speed = 21 km/hr
distance for the second half = speed*5, where speed = 23.8 km/hr

so, to find the total distance, add the two distances together
