Question

a train laves los angles at 2pm, heading north at 50mph. If the next train leaves 3 hours later and heads north at 60 mph, at what time will the second train catch up with the first?

Answer 1

8 am

Explanation:

First train has a 50 m/hr x 3 hr = 150 mile head start

Second train is going 60 - 50 = 10 m/hr faster and will close this 150 mile distance

in 15 hours to catch the first train

2pm + 3 hours + 15 hours = 8 am
