Lionel left his house and walked towards Walt's house, 48 miles away. Two hours later, Walt left his house and ran towards Lionel's house. If Lionel's speed was 4 miles per hour and Walt's 6 miles per hour, how many miles had Lionel walked when he met Walt?
Hi - can someone please explain the step by step approach to solve this question? Its in the GMATCub Test m03.
Unless, my approach is wrong this is how I solved this:
Lionel Speed = 4mph
Walt speed = 6 mph
Let T be the time taken by Lionel, then T-2 will be the time taken by Walt
4T + 6(T-2) = 48 [ Rate = Distance/Time and therefore Distance = Time * Rate]. I solved this to get
Lionel's speed = 4
Distance Lionel covered = 4*6 = 24
