a car is driving at a speed of 60 mi/h. what is the speed of the car in feet per minute?

Converting 11.5 km to cm, we have 11.5 km= (100cm /  1 meter) * ( 1000 meters / 1 km) = 1150000cm

So the scale is 1150000 : 1

So 5.5 cm * 1150000 = 6325000cm = 6325000/100000 = 63.25 km= 63.3 km (to the nearest tenth of a km)

A car traveling at 60mph has a ft/sec rate given by:

60mph * ( 5280ft / 1 mile) * (1hr / 3600sec ) = 88 ft/sec
