Question

Alexia ran three laps around her neighborhood. Each lap is 1 3/8miles. Which is the best estimate of the number of miles that Alexia ran?

Answer 1

She ran 4 1/8 miles or 4 and 220 yards

Answer 2

Answer: The best estimate of the number of miles that Alexia run is 4 miles.

Explanation:

Since we have given that

Length of lap is given by

`1(3)/(8)\ miles`

Number of laps around her neighborhood = 3

So, Total number of miles that Alexia ran is given by

`1(3)/(8)* 3\\\\=(11)/(8)* 3\\\\=(33)/(8)\\\\=4(1)/(8)\ miles\approx 4\ miles`

Hence, the best estimate of the number of miles that Alexia run is 4 miles.
