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?
<pre>
The lion is approaching the zebra at the rate of 50-40 or 10 mph.
10 mph is:

10  miles per   1 hour, which is
10  miles per  60 minutes, which is
 1  mile  per   6 minutes, which is
1/4 mile  per 6/4 minutes, which is
1/4 mile  per 1.5 minutes.

Answer: 1.5 minutes.

The other tutor says a lion cannot run 50 mph.  According to this
site

a lion can run 50mph and a zebra can run 40mph,
just as this problem states.
