Question

Express the distance traveled as a function of the number of hours at the average speed. The morris family is traveling from providence to Fredericksburg. Given city traffic they will average 45 mph

Answer 1

Dist = 45 m/h * x h

Explanation:

We know a speed is a measure of distance over time: speed = dist / time

In this case, we are looking for a distance expressed in terms of time.

So, we only need to modify the formula a bit: dist = speed * time

We don't know the time (which will be a variable), but we know their speed. So, the formula becomes:

Dist = 45 m/h * x h

Enter the number of hours in the formula and that will give you an approximation of the distance traveled within that time (approximation since our result will be rely on an average).
