Question 932994: The distance between towns A to B is equal to 48 km. The road connecting A and B is not flat and consists of segments that go either uphill or downhill only. A cyclist rode his bike from A to B and back in 3.5 hours. It is known that the cyclist was moving uphill at a speed 24 km/h. At what speed did the cyclist move downhill? Answer by TimothyLamb(4379) (Show Source):
You can put this solution on YOUR website! x = downhill speed
y = uphill speed = 24 kph
---
s = d/t
---
1/24 + 1/x = 3.5/48
1/x = 3.5/48 - 1/24
x = 1/(3.5/48 - 1/24)
x = 32
---
answer:
x = downhill speed = 32 kph
