Question

Josephin is going on a run around the lake. she knows the distance around the lake. but she would like to complete her run in a certain amount of time. josephine knows she can use the formula d= rt.

which equation correctly rearranges the formula to find the time it will take her to run around the lake?

look at picture and tell me if it is a, b, c, or d.

Answer 1

A.
`t = (d)/(r)`

Explanation:

Given

`d = rt`

Required

Determine the time

From the question, we understand that:

`d = distance`

`r = rate`

`t = time`

This question implies that we make t the subject of formula.

`d = rt`

Divide both sides by r

`(d)/(r) = (rt)/(r)`

The equation becomes:

`(d)/(r) = t`

Reorder the equation.

`t = (d)/(r)`

The correct option is (a)
`t = (d)/(r)`
