Question

A commuter train leaves the Metro transit station at precisely 10:00 AM. You intend to board the same train at the next stop in Whistleville, located 14 miles away from the Metro transit station. The average speed of the commuter train is 35 mph. It takes you five minutes to walk from your apartment to the platform in Whistleville. What time should you leave the apartment in order to arrive at the platform at the same time as the train?

Answer 1

Distance between Metro  transit station to Whitstleville = 14 miles
Average speed of train = 35 mph
Time of departure from metro = 10.00 AM
Time to the next station, t= d/s = 14/35 = 0.4 hrs = 24 minutes
Since it takes 5 minutes to the station, the traveler leaves the apartment at,

10.00 AM + (24-5 minutes) = 10.19 AM
