A stagecoach left Drygulch traveling east at 3 km per hour. Two hours later, another stagecoach left Drygulch traveling in the same direction at 40km per hour, How many hours had the first one been traveling when the second one caught up?

Answer 1

d1 = 3km/h * 2h = 6 km Head start.

d2 = d1 + 6km
40t = 3t + 6
37t = 6
t = 0.162 h = 9.73 min. to catchup.

2 + 0.162 = 2.162 h = Hours travelled by
the first stagecoach.

Note: Please check the speed of the 2nd coach; because forty doesn't look right.
