What is the average acceleration of a car that goes from rest to 60 km/hour in 8 seconds?

Question

do i have to convert units, btw. an explanation of how would be goood tooo!

Answer 1

60 km/hour in 8 seconds

8 seconds is 8/3600 hour

the average A = 60 km/hr divided by 8/3600 hour = 0.1333 km/hr²

or you can do it in seconds

60 km/hr x 1 hr / 3600s = 0.0166667 km/sec

0.0166667 km/sec / 8sec = 0.0020833 km/s²
