Question

need help. if u know plz help

Answer 1

0.5 mile = 1/2 mile

 

The speed is 1/2 mile divided by 6 seconds = 1/2 divided by 6

 

                                                                = 1/2 divided by 6/1

                                                                 

                                                                 = 1/2 * 1/6

                    

                                                                   = 1/12

 

1/12 miles per second = 0.083  miles per second

 

In miles per hour that is:

 

 1/12 miles per second * 60 seconds per minute * 60 minutes per hour = 1/12 * 3600 = 300 mph
