I am learning about rate of change, please help

For 10. the answer is 0, and 150 miles (assuming the 25 is in miles per hour)

For 11. the answer is 0, and 22.5 tacos

Step-by-step explanation:

Rate of change is equal to the change y over the change in x, or in this case, the change in speed over the change in time, because the rate for both problems is "constant", there is no change in speed. To find the number of miles driven you need to multiply the time passed (6 hours) by the speed (25 mph), 6 x 25 = 150. The number of tacos eaten is times passed (9 minutes) multiplied by the speed he is eating tacos (2.5 tacos per minute), 2.5 x 9 = 22.5. Hope this helps!
