A child can run 5 blocks in 2 minutes. How long does it take the child to run 8 blocks, at the same speed?
The child can run 8 blocks in 3.2 minutes. You get this answer by multiplying 1.6. You would have to do this on the top and bottom of the numbers. The first step is 5 x something will give you 8. Well try it the other way if you can´t find it. 8/5=1.6 5 x 1.6=8. Then all you have to do on the top is 2 x 1.6 to get your answer.
