Quote by: cynqsh66Hello,

Can someone help me with the following question?

Q1. At 3p.m., a regular train left Town A for Town B at an average speed of 75km/h. At 7pm, an express train left Town A for Town B travelling at a constant speed, on parallel path. If the express train took 5Hr to catch up with the regular train, find its average speed.

Q2. Michael and Ron have a bicycle race. Michael cycles at a speed of 48km/h. Ron cycles at a speed of 36km/h. If Michael let Ron start 1h 45mins before him, how long will he take to catch up with Ron?

Thank you very much for helping.
