Bob and Tom live 62 km apart. At 7 AM Bob left his home cycling towards Tom’s home at 20 km/h.
At 8 AM, Tom left his home cycling towards Bob’s home at 8 km/h. Calculate the time when the two meet.
~~~~~~~~~~~~~
In one hour, from 7 am to 8 am, Bob covers 20 kilometers, and at 8 am the distance between them is 62-20 = 42 kilometers.
Starting from 8 am, their approaching rate is 20 + 8 = 28 km/h.
Hence, they will meet in = 1.5 hours = 1 hour and 30 minutes after 8 am, i.e. at 9:30 am. ANSWER
