Okay so 120m per 8 sec you are going to divide 120 / 8 = 15 your answer is 15 15m per sec if you wanna double check that then you will want to go backwards 15 x 8 = 120 there you have it your answer is correct :) 15m per sec i really hope i helped you out in some type of way :)))
So to get this the easiest way would be to: -put 90,000,000 over 186,000 and cancel out zeroes so you have 90,000 divided by 186 ( so it makes more sense in long division later) -Then divide 90,000 by 186 -get 483.87 seconds Hope this helped!
