a lap around a track is 2/5 of a mile.
how many laps is a 1 1/2 mile race
To find out how many laps are there in a 1 1/2 mile race, you need to divide the total distance of the race by the distance of one lap.
Given that one lap around the track is 2/5 of a mile, you can set up the following equation:
1 1/2 miles = (2/5 miles per lap) * x laps
To solve for x, you can multiply both sides of the equation by the reciprocal of 2/5, which is 5/2:
1 1/2 miles * 5/2 = (2/5 miles per lap) * x laps * 5/2
(3/2) * (5/2) = x
15/4 = x
Therefore, a 1 1/2 mile race is equal to 15/4 or 3 3/4 laps around the track.
