Question

Antony and Lily started moving in opposite directions from the same point at the same time. If Antony was biking with average 12 mph speed and Lily was walking by 4 mph, how soon the distance between them will be 76 miles?

Answer 1

4 hours and 45 minutes

The number of miles increasing each hour is 16, 16 times 4 is 64, and to get to 76, you add an extra 3/4 of an hour, which is 45 minutes.
