Question

Mr. Ledesma is running the marathon. The distance for the marathon is 26.2 miles or 46,112 yards. If his stride length is 1.5 yards per stride, how many strides did it take him to complete the race in a direct line?

Answer 1

It took Mr. Ledesma 30742 strides to finish the race.

Explanation:

Since Mr. Ledesma walks 1.5 yards per stride and the total distance of the marathon is 46112 yards, we can use a proportion to determine how many strides (x) it took him complete the race in a direct line:

46112 yd / x strides = 1.5 yd / 1 stride

(46112/x = 1.5) * x

(46112 = 1.5x) / 1.5

Strides = 30741.33333

• Mr. Ledesma can't walk a fraction of a stride and usually we'd round down to 30741.

• However, 30741 * 1.5 = 46111.5 yd, meaning 30741 strides wouldn't be enough to finish the race.

• If we round up, we get 30742 * 1.5 = 46113 yd.

This means that it would take Mr. Ledesma 30742 strides to complete the race in a direct line.

Answer 2

≈ 30,741.33 strides

Explanation:

Number of Strides = Total Distance / Stride Length

Number of Strides = 46,112 yards / 1.5 yards/stride

Number of Strides ≈ 30,741.33 strides
