Y= 4/10x 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?
The constant speed of the van can be calculated by converting the number of kilometers traveled in x minutes to the number of kilometers traveled in hours.
Since there are 60 minutes in an hour, we can convert x minutes to hours by dividing x by 60.
y = (4/10)x
y = 4x/10
y = 0.4x
Now, let's convert this to hours:
y = 0.4(x/60)
y = 0.4(x/60)
y = 0.4(x/60)
y = 0.4(x/60)
Thus, the constant speed of the van is 0.4 kilometers per hour.
