Question

Please help! The distance a car travels, d, is proportional to a constant rate of speed, r, at different times, t.

Which equation shows the relationship between the distance the car travels and the speed of the car?
a. d=rt
b. d=r+t
c. d=r-t
d. d= r/t

Answer 1

There's a saying to this kind of equation: Rate + Time = Distance and B best fits the saying, so B must be right (Don't quote me on that, it may be wrong)
