At 7am,Roy started his run from Town Forks to Town Spoons at an average speed of 16km/h. 45 minutes later,Soy started cycling from Town Spoons to Town Forks at an average speed of 24km/h.Both Roy and Soy reached their respective destination at the same time. What was the time taken by Roy to travel from Town Forks to Town spoons?
Ans : 2hr 15 minutes
How to do?
Tks

Answer

Distance Roy travelled after 45 min = 16 x (45/60) = 12km
Let d be the remaining distance Roy needed to travel to Town Spoons.
d / 16 = (12 + d) / 24              (Same time taken to reach destination)
24d = 192 + 16d
d = 24
(24+12)/16 = 2.25
Roy travelled from Town Forks to Town Spoons in 2.25h = 2 h 15 min
