police estimate the speed a car has been travelling by using the length of the skid marks. A formula used for this purpose is v=-7+8.2square root d, d>0, where v is the speed in kilometres per hour, and d is the length of the skid marks, in metres. 

a: Solve formula for d

b: For a car braking from a speed of 90km/h, what are the length of the skid marks to the nearest metre.

c: What would be the speed of the car, to the nearest kilometre per hour that would have created 150 skid marks?
