Question 10

A car starts driving at noon.

Suppose thatR(t)gives the speed of the car in miles per hourtseconds after noon, and thatS(m)gives the speed of the car in kilometers per hourmminutes after noon.

There are about 1.6 kilometers in a mile. There are 60 minutes in an hour.

Which of these is correct?

Group of answer choices

S(m) = 1.6 R(60t)

S(m) = 1.6 R(t/60)

S(m) = R(60t) / 1.6

S(m) = R(t/60) / 1.6
