Question

A bus travels with a constant speed of 60 miles per hour. How long will it take to travel 75 miles?

Answer 1

75 minutes

Explanation:

60/1=75/x

cross product

1*75=60*x

75=60x

x=75/60

simplify

x=5/4

Assume that x=4/4=1 hour, so 5/4 is 75 minutes since 60/4=15 and 15*5=75.

Answer 2
