Convert each values accordingly
1 step = 42 inches
1 mile = 63360 inches
Thus
1 mile (63360 inches/ 1 mile) (1 step / 42 inches)
This helps to eliminate the units and determine which unit is left.
(63360/ 42 ) steps = 1, 508.6 steps.
Rounding up the decimal thus gives a total of 1, 509 steps in 1-mile run.
