Problema Solution
a bicycle rider covers his onward journey from A to B at 10km/hr and during the return journey from B to A he covers the same distance at 8km/hr.if he finishes the onward and returnjourney in 4 hours,then the total distance covered by him during the entire journey wil be?
Answer provided by our tutors
Let the total distance one way be x.
So, x/10 + x/8 = 4.
(4x+5x)/40 = 4.
9x/40 = 4.
9x = 160.
x = 160/9 = 17.78.
So, the total distace covered will be 2x = 35.56 km.
