Question 133055: Hello please try to solve my question
A bus travels at 36 km\h and arrives at its destination half an hour late. If it travels at 42 km/h, it arrives at the same distination half an hour earlier. Find the journey's distance.

Let d = distance and t = time to arrive
d/(t+1/2)=36
d/(t-1/2)=42
then
36(t+1/2)=42(t-1/2)
36t+18=42t-21
-6t=-39
t=13/2=6.5
d=36(13/2+1/2)=36(7)=252
Answer: distance = 252 kms
