Question

A police officer was sent to investigate a car accident. He knows the speed of the car, s, can be measured with the equation s = at, where a is the rate of acceleration and t is the time. Which equation can he use to solve for the rate of acceleration?

a = s – t

a = t – s

a = s ÷ t

a = st

Answer 2

@e.cociuba

Answer 3

a = s ÷ t
Take the information that the paragraph provides you, apart. You will come out with your answer as "a" equals "s" divided by "t".

Answer 4

A?

Answer 5

I agree with @e.cociuba but you can do it a different way also. You can take the equation s=at and divide both sides by s so it would be \[\frac{ s }{ at }\] then multiply both sides by a to get \[a=s \div t\]

Answer 6

it isn't A

Answer 7

"where a is the rate of acceleration...."
So you know by this that it's:
a/at
Multiply both sides to get your answer:
a= s/t

Answer 8

Yup, agreed @esshotwired :D

Answer 9

It's C!
