The equation y = 6/20
x describes the number of kilometers y that a van travels in x minutes. What is the constant speed of the van in terms of hours? Use pencil and paper. Express the speed in three different ways.
To express the speed of the van in terms of hours, we need to find the conversion factor from minutes to hours and divide the kilometers by this factor.
There are 60 minutes in 1 hour, so the conversion factor is 1/60.
Dividing y = 6/20 by the conversion factor, we get:
(6/20) ÷ (1/60) = (6/20) * (60/1) = 18/1
Therefore, the constant speed of the van in terms of hours is 18 kilometers per hour.
Three different ways to express the speed are:
1. 18 km/h
2. 18 km/hr
3. 18 kilometers per hour
