Question

Lin ran 2 3/4 miles in 2/5 of an hour, Noah ran 8 2/3 miles in 4/3 of an hour, how far would Lin run in 1 hour?

Answer 1

`6(7)/(8)\ miles`

Explanation:

Given that Lil's distance in 2/5 hrs is 2 3/4hrs

-Let x be the distance ran in 1 hr.

#We equate and cross multiply to solve for x as follows:

`(2)/(5)\ hrs=2(3)/(4)\\1\ hr=x\\\\\therefore x=2(3)/(4)/(2)/(5)\\\\=6(7)/(8)\ miles`

Hence, Lil can run 6 7/8 miles in 1 hr.
