help!

Answer 2

OK first i would convert to mph

Answer 3

so 4.5miles in .25 of an hour, you can multiply 4.5*4 to get mph

Answer 4

so 18 mph

Answer 5

then convert to feet per hour by multiplying by 5280 which is the feet in a mile
18*5280=95040

Answer 6

then divide by the seconds in an hour so 60*60=3600
95040feet per hour /3600 seconds per hour =26.4feet per second
