A certain car is capable of accelerating at a rate of +0.60 m/s2. How long does it take for this car to go from a speed of 20 mi/h to a speed of 65 mi/h?

acceleration = change of speed / time
but make sure the units are consistent.
change of speed
= (65-20) mph
=x m/s (find x)
0.60 = x/t
or
t=x/0.6 seconds
