a railroad construction crew can lay 1 1/4 mi of track in one day. at that rate , how many miles of track can be laid in 10 days?
To find out how many miles of track can be laid in 10 days, we need to multiply the amount of track laid in one day by the number of days.
The amount of track laid in one day is 1 1/4 mi, which can also be written as 5/4 mi.
So, the number of miles of track that can be laid in 10 days is:
(5/4 mi) * 10 days = 50/4 mi
Simplifying the fraction, we get:
50/4 mi = 12 1/2 mi
Therefore, the railroad construction crew can lay 12 1/2 miles of track in 10 days.
