Question

Rosetta drove her car 160 miles in 2 hours. Which of the following correctly expresses her rate as a ratio?

Answer 1

Rosetta drove her car 80 miles in one hour. Assuming that you ate talking about miles per hour you decide 160÷2=80 therefore, she drove 80 miles per hour (80/mph)

Answer 2

The correct answer is,

The rate of ratio of Rosetta's car = 80 miles per hour

Explanation:

Formula:-

Speed = Distance /Time

It is given that,Rosetta drove her car 160 miles in 2 hours.

To find the speed of car

Speed = Distance /Time

Distance = 160 miles

Time = 2 hours

Speed = 160/2 = 80 miles per hour.

Therefore the rate of ratio of Rosetta's car = 80 miles per hour
