A boy walked for 4 hours and cycled for 3 hours,covering a total distance of 74 kilometers,later he walked for 2 hours and cycled for 4 hours ,covering 82 kilometers,what were his average speed of walking and his average speed of cycling if his speed was constant in the two cases?

Answer 1

4w+3c = 74
2w+4c = 82

c=18, w=5

if the speed was constant, there's no need to talk about an average speed. However, in real life such speeds are never constant, so they should have just asked about the average speed.
