If we are speaking about a constant speed, it is defined as a distance traveled divided by a time spent. In the given problem, the distance is given miles) and the time
=
hours and
minutes is given, too. But for division we have to transform the time into some single units, for example to hours.
There are minutes in one hour, therefore
minutes is equal to
so
hours. Thus the speed
(miles / hour). Actually this value may be the answer, but we also may want this speed to be expressed in, say, standard meters per second.
To perform this conversion, recall that mile
meters and
hour =
seconds. Therefore
