Preston drove to his new college and then back home. Round trip he traveled 212 miles. Preston's car gets 35 miles per gallon. If Preston needs to make 12 round trips a year, how much will it cots him in gas if each gallon of gas costs $3.60

A police chase covering 225 miles at a constant speed of 75 miles/hour will last 3 hours.

Step-by-step explanation:

If the car is traveling at a speed of 75 miles/hour and has traveled a distance of 225 miles, we can solve for the time taken by using the equation

d = r*t

where d is our distance in miles

r is the rate of travel in miles/hour, and

t is the time taken in hours

In this case,

d = 225 miles, and

r = 75 miles/hour

Let's plug these into our equation

225 miles = (75 miles/hour) * t         Divide both sides by 75 miles/hour

Our miles units will cancel out, leaving us with

3 hours = t

Therefore, a police chase covering 225 miles at a constant speed of 75 miles/hour will last 3 hours.
