Answer:
3771.43 times [roughly 3771 times]
Explanation:
The unit ratio given is:
140 feet : 20 times
How many feet is that per 1 time wheel turning?
140/20 = 7 feet
So, each wheel revolution covers 7 feet [1 time turn = 7 feet]
Now,
We want the number of times wheel turns in 5 miles. First, converting 5 miles to feet:
1 mile = 5280 ft
5 mile = 5 * 5280 = 26,400 feet
Hence, the number of times it turns in 5 miles is:
26,400 feet / 7 feet = 3771.43 times [roughly 3771 times]
