A distance of 150 km was covered by a motorcyclist traveling at an average speed of 75 km/h, by a bus at 60 km/h, a truck at 50 km/h, and a bicyclist at 20 km/h. How much time did each require to travel the entire distance? Explain why speed and the time needed to travel 150 km are inversely proportional quantities?

answer:
time taken by motorcycle= dist/speed= 150/75 = 2 hrs
time taken by bus = 150/60= 2.5 hrs
time taken by truck=150/50=3 hrs
time taken by bicyclist=150/20= 7.5 hrs
as speed =dist/time therefore time and speed are inversely proportional for same distance.
