The equation y= 10/20x 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?

To express the speed of the van in terms of hours, we need to convert the time from minutes to hours.

We know that 1 hour is equal to 60 minutes.

So, to convert x minutes to hours, we divide x by 60.

Therefore, the equation y = (10/20)(x/60) can be simplified to y = (10/1200)x, since 10/20 simplifies to 1/2 and x/60 simplifies to x/1200.

Therefore, the constant speed of the van in terms of hours is 1/1200.
