Best ResponseYou've already chosen the best response.0Look at the units. The answer has to be in miles/hour. So you need to divide the number of miles by the number of hours. But there's a twist. The time is given in seconds so you first have to convert it to hours. Try it on your own and see how you get along. I'll be here to help if you need it.
