Question

Holly can walk 3.75 miles per hour. At that same rate, how far can she walk in 2.5 hours?

A. 8.375 miles
B. 6.25 miles
C. 7.25 miles
D. 9.375 miles

Answer 1

3.75 / 1 = x / 2.5....3.75 miles to 1 hr = x miles to 2.5 hrs
cross multiply because we have a proportion
(1)(x) = (3.75)(2.5)
x = 9.375 <==
