Question

It takes a street sweeper 27 minutes to travel 3 miles. If the street sweeper travels at the same speed, how many miles will the street sweeper travel in 45 minutes?

Answer 1

x=5 miles

Explanation:

first you have to get his constant speed or his rate

rate = time / distance

so in this case 27/3 which equals 9,

1 mile = 9 minutes

then, you would set up your equation

9 minutes = 1 mile

45 minutes = x miles

cross multiply , 45 * 1= 45 , then divide by 9

x = 5 miles
