Answer:
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.

if we use the other shapes the 3-D figure will be incomplete.
Hope I am correct and it helps! ;) <3
Answer:
<u>C and D</u>
Step-by-step explanation:
<u>D.</u> A negative times a positive gives you a negative, so the first 2 fractions will still be negatives after they get out of the parenthesis
<u>C.</u> The 4/7 and -4/7 cancel out
