Answer:
Rate: 56.25 mi/h
Distance traveled in 3 hours: 168.75 mi
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:
[tex]90\text{ km/h }\times\frac{1\text{ mile}}{1.6\text{ km}}=\text{ 56.25 miles/h}[/tex]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:
[tex]56.25\text{ mi/h }\times\text{ 3h = 168.75 mi}[/tex]Therefore, the answers are:
Rate: 56.25 mi/h
Distance traveled in 3 hours: 168.75 mi
