Question 758557
A Lion runs 50 miles per hour in pursuit of a zebra running at 40 miles per hour. If the initial distance between them was a quarter of a mile, how long will it take for the lion to catch the zebra?
------------------
The lion "gains on" the zebra at 10 mi/hr (50 - 40)
d = r*t
t = d/r
t = (1/4)/10
t = 1/40 hour
==================
PS  Lions don't run at 50 mi/hr
