Distance = S, Velocity = V, Time = T
V = S/T
V = 28/30 min
Multiply x 2/2 (= 1 )
V = 28/30 x 2/2 = 56 m/60 min
V = 56 mph

as 30 minutes is half of an hour you need to double the number of miles the car travelled in half an hour to work out the speed:
28 x 2 = 56mph

28 / 30 x 60 = 56 mph

30 minutes is 1/2 hour. So multiply the distance by 2.... 56 miles per hour.

28+28 = 56. 30 Minutes = 1/2 an Hour (0.5) so 28(2)=56 to get 56 as the mi.

28 miles in 1/2 an hour, therefore in 1 hour 28x2 = 56 mph
