Answer:
Average Rate = 55mph
Step-by-step explanation:
Now it’s time to tackle the original question. Going from point A to point B, the cheetah traveled at an average rate of 70 mph. Returning to point A, the cheetah traveled at an average rate of 40 mph.
Can we say that this cheetah’s average rate was 55 mph?
a.The average rate for the trip is equal to the total distance traveled divided by the total time traveled.
Average Rate = 70+ 40/2= 110/2 = 55mph
Yes the average rate of the cheetah is 55 mph
The following equations represent the distance traveled on each leg of the trip.
First leg of trip: td=r1 t1= 70*t
Second leg of trip: td=r2 t2= 40*t
Write an equation for the average rate for the trip. Remember, the cheetah runs from point A to point B and back to point A.
Total distance = r1 t1+ r2 t2
Average rate = Total distance / total time
= r1 t1+ r2 t2/ t1+ t2
=70t+ 40t/ 2t
=110t/2t
= 55mph
Answer:
the answer is 55 mph
Step-by-step explanation:
Average rate = Total distance / total time
= r1 t1+ r2 t2/ t1+ t2
=70t+ 40t/ 2t
=110t/2t
