Question

a railroad construction crew can lay 1 1/4 mi of track in one day. at that rate how many days will it take to lay 10 mi of track?

Answer 1

To find out how many days it will take to lay 10 miles of track, we need to divide 10 by 1 1/4.

To divide a whole number by a fraction, we need to multiply the whole number by the reciprocal of the fraction.

The reciprocal of 1 1/4 is 4/5.

Therefore, we can calculate:

10 / (5/4) = 10 * (4/5) = 40/5 = 8.

So, it will take the railroad construction crew 8 days to lay 10 miles of track.
