A vehicle travels on the highway at a rate of 55 mi/hr. How long does it take the vehicle to travel 45 miles?

speed = 55mi/HR, distance is 45 miles and time is not given so what we are finding is the time the vehicle used when travelling 45miles at a rate of 55mi/hr. distance=speed×time. 45=55×time(t). 45=55t. now divide 45 by 55t to get time. which is 0.82.

ratio is 2 : 9

the answer is three

13.5 : 3
