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

In the first 2 hours Lionel at the rate of 4 miles per hour covered distance=rate*time=4*2=8 miles. So, the distance between him and Walt was 48-8=40 miles when Walt left his house. Now, their combined rate to cover this distance was 4+6=10 miles per hour, hence they will meet (they will cover that distance) in time=distance/rate=40/10=4 hours. Total time that Lionel was walking is 2+4=6 hours, which means that he covered in that time interval distance=rate*time=4*6=24 miles.

First step - same as Bunuel suggested In the first 2 hours Lionel at the rate of 4 miles per hour covered distance=rate*time=4*2=8 miles. So, the distance between him and Walt was 48-8=40 miles when Walt left his house.

Then apply the formula Time to meet = Distance between L and W/(Rate of L + Rate of B) Time to meet = 40/(4+6) Time to meet = 40/10 Time to meet = 4 hrs

Lionel will travel 16 miles in 4 hrs and he has initially traveled is 8miles. So 16+8=24 miles

The First 2 hours Lionel covers- 8 miles (4 X 2).................... (1) The remaining distance= 48-8= 40 miles. Since they are moving in opposite directions the distance between them increases at the rate of 10 miles/hr (6+4) Now both of them meet at 40/10= 4 hours Now in 4 hours Lionel travels 4X4= 16 miles.............. (2) therefore, Total distance Lionel would have travelled (1)+(2)=16+8= 24 miles.

I tried to solve this problem by visualising it a bit more.

Rate L = 4m/hour Rate W = 6m/hour

I made a small table ( which is possible, since they are working with easy numbers here). In the first column the hours, second counting (second column) is the new counting of hours for W.) Since the third hour of L can be considered as the first hour walking for W.
