Question

An object traveled for 3 hours at a rate of 30 mile/hr, and then for another 2 1/4 hours at a rate of 10 1/2 miles/hr. How many total miles did the object travel?

Answer 1

113.625 miles

Explanation:

3 hours at a rate of 30 mile/hr : 3*30=90 miles

2 1/4 hours at a rate of 10 1/2 miles/hr= 2 1/4 *10 1/2= 2.25*10.5=23.625

total miles the object traveled : 90+23.625=113.625 miles
