Question

Which of the following equations is true? A. distance = rate ⋅ time B. rate = distance ⋅ time C. time = distance ⋅ rate D. none of the above

Answer 1

A. distance = rate * time (
`d=rt`)

Step-by-step explanation:

it's always been taught as distance equals rate multiplied by time.

B can't be correct (
`rate=distance*time`) because in order to find rate you would do
`(distance)/(time)=rate` so B is wrong.

C also can't be correct (
`time=distance*rate`) because in order to find rate you would do
`(distance)/(rate)=time` so C is wrong.

D is wrong since A is the standard and correct solution/equation of finding distance, rate, or time.

Answer 2

B

Step-by-step explanation:

You can use the equivalent formula d = rt which means distance equals rate times time. To solve for speed or rate use the formula for speed, s = d/t which means speed equals distance divided by time.
