On a rally, A drives at 60 mph and arrives an hour earlier than B who averages 50 mph. How long is the rally (in miles)?
posted Oct 5, 2017

60*x = 50*(x+1) [Distance Traveled in both cases are the same][x => Time taken by A to reach the end]
60x - 50x = 50
10x = 50
x = 5 hours
Therefore the rally is 60*5 = 300 Miles long.

the rally is 300 Miles long.
