Acar was stopped at a red light. when the light turns green, the car reaches a speed of 21 miles per hour in 8 seconds. what is the acceleration, to 1 decimal place?

21 / 8 = ?

21 / 8 =  2.625

2.625 = 2.6

2.6 miles acceleration per second.

I hope this helps!

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.
