The distance d that a car can travel in a certain amount of time t can be found by multiplying the rate of speed r by the travel time. if a car has already travel 4 miles, the formula for the total distance travel is d= rt + 4. which of the following gives the value of r, in terms of d and t?

If the formula of the the total distance travel is:

   (1)

And we want to know the value of in terms of and , we have to clear from equation (1):

>>>>This is the value of

Explanation:

The formula for the total distance travel is

We need to find the value of r, in terms of d and t.

Subtract 4 from both sides.

Divide both sides by t to find the value of r.

Interchange both sides.

Therefore, the value of r, in terms of d and t is .

answer:

2
