Question

The distance formula states that distance (d) is equal to the product of rate (r) and time (t).

Which equation could be used to solve the problem?
John ran at a constant rate of 200 mph. How many minutes did it take john to run 500 m?

A. t=500/200

B. t=500d/200

C. t=200/500

D. t=200r/500

Answer 1

Answer: B

Step-by-step explanation:

d = t * r

t = d/r

t = 500d/200

Answer 2

A. t=500/200

Explanation:

If Distance = d

Product Rate = r

Time = t

and the equation states that;

d = r x t

then by dividing the equation by r we get;

t = d / r

By putting in the values of d = 500 and r = 200 in the above equation we get;

t = 500 / 200
