A backpacking club can average 2 1/2 miles per hour. At that rate, how long will it take for a hike of 8 3/4?

Question

miles?

Answer 1

2 1/2 = 5/2
8 3/4 = 35/4

35/4 divided by 5/2 which is also the same as...
35/4 x 2/5.

So, 35/4 x 2/5 = 70/20 =3 1/2 hours

3 1/2 hours is the answer!

Answer 2

will 8 3/4 is 8.75 and 2 1/2 is 2.5.....

2.5 x = 8.75
divide both side by 2.5
x =3.5......mean 3.5 hrs.....which mean 3 hrs and 30 minutes
