Using
the distance formula,
it can be demonstrated how any one of the variable values can be found. |
Given that d = r t then r = d / t and t = d / t. Stated in words: If
distance is the product of rate and time, then, to find either the
rate or the time, simply divide the distance by the one known value. |
An airplane traveled 480 miles in 3 hours. What was its speed? 480 / 3 = 160 mph |
A rocket traveled at 1200 mph for a distance of 14400 miles. How long did it take to travel that distance? 14400 / 1200 = 12 hours |
The same plane went 600 miles in 4 hours. What was its speed? |
If the rocket traveled at a speed of 1600 mph for a distance of 5600 miles, how long would it have been traveling? |
