Answer:
17.6 laps
Explanation:
Total distance to be covered = 2 miles
distance coved in each lap = 400 yards
We know that 1 mile = 1760 yards
therefore, 4 miles will make = 4×1760
= 7040 yards.
Number of laps to be taken
= Total distance to be covered ÷ distance coved in each lap
= 7040/400 = 17.6 laps
Therefore, it would take 17.6 laps to cover a distance of 4 miles if lap were 400 yards.
