Question

A car 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?

Answer 1

21 divided by 8 = 2.625

Then round 2.625

                    2.630

Next you takeaway everything after 0.030

To get the awnser of 2.6

Answer 2

21 / 8 = ?

21 / 8 =  2.625

2.625 = 2.6

2.6 miles acceleration per second.

I hope this helps!
