Question

A car is traveling at a rate of 90 kilometers per hour. What is the car’s in miles per hour? How many miles will the car travel in 3 hours? In your computations, assume that 1 miles is equal to 1.6 kilometers. Don’t round your answer. Rate: _ mi/h Distance traveled in 3 hours: _ mi

Answer 1

Rate: 56.25 mi/h

Distance traveled in 3 hours: 168.75 mi

Step-by-step explanation:

We know that 1 mile is equal to 1.6 kilometers, so, we can change the rate of 90 kilometers per hour to miles per hour as:

`90\text{ km/h }*\frac{1\text{ mile}}{1.6\text{ km}}=\text{ 56.25 miles/h}`

Now, we know that every hour the car travel 56.25 miles, so, the number of miles that the car travel after 3 hours is:

`56.25\text{ mi/h }*\text{ 3h = 168.75 mi}`

Therefore, the answers are:

Rate: 56.25 mi/h

Distance traveled in 3 hours: 168.75 mi
