Answer 1

First you need to figure out how many meters and in a mile then find out how many secs are in an hour

Answer 2

1609 meters in a mile 3600 seconds in an hour. I already know that.

Answer 3

Ok so Ken is moved
1000 meter in 7.045 secs. In terms of miles how many miles is that >?

Answer 4

1000/1609

Answer 5

ok, reduce that to a decimal that will be your top answer. Now to work on the bottom. You mentioned there were 3600 sec in an hour he moved for 7.045s. so 3600/ 7.045 = 511.0007 thats how many "cycles" or 7.045 secs occur concurrently in an hour. that answer needs to be multiplied by the top answer. to determine how fast hes moving in miles per hour

Answer 8
