a model airplane flies 18 feet in 2 seconds what is the planes speed per miles an hour?
how do i do these

1.
One tablespoon is equal to 15 ml.
One US gallon has 3.785 litres = 3785 ml.
One mile has 1760 yards.
So the distance per gallon
= (3785/15)*125 yds/1760 yds/mile
= ? miles
2. 1 mile = 5280 ft
1 hour = 3600 s.
Try to work out the conversion, one step at a time.
