To cover 5 miles the wheel covers 3771.42 (approx) turns.
Step-by-step explanation:
Given,
In 20 times turns wheel covers 140 feet.
1 mile = 5280 feet
To find the number of times wheels turns to cover 5 miles.
We will apply unitary method.
Now,
5 miles = 5×5280 feet = 26400 feet
140 feet covers in 20 turns
1 feet covers [tex]\frac{20}{140}[/tex] turns
26400 feet covers in [tex]\frac{20}{140}[/tex]×26400 turns
= 3771.42 (approx) turns
