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? So what is:

Question

The constant speed of the van is __ kilometers per hour.

Answer 1

To convert minutes to hours, we divide by 60 since there are 60 minutes in an hour.

First, let's simplify the equation y = 10/20x:

y = (1/2)x

This equation tells us that the van travels at a speed of 1/2 kilometer per minute.

To convert this speed to kilometers per hour, we need to multiply it by 60 since there are 60 minutes in an hour:

(1/2) * 60 = 30/2 = 15 kilometers per hour

Therefore, the constant speed of the van is 15 kilometers per hour.
