Question

carla is renting a canoe it cost $60 for 2 hours and $90 for 5 hours what is the rate of change or slope for this situation?

Answer 1

Rate of Change = $10 per hour

Explanation:

Rate of change, or slope, technically means change in y-coordinates by change in x-coordinates.

Here, by rate of change, we mean the change in cost of renting per unit time (per 1 hour).

So we see that rate changes by 30 [90 - 60 dollars] when time changes by 3 [ 5 - 2 = 3 hours]

Thus, we can say the rate of change (per unit time) would be:

30/3 = 10 dollars per hour

Rate of Change = $10 per hour
