First convert 55 mph to ft/sec:
55 mi/hr=55 mi/hr*(1hr/3600s)*(5280ft/mi) = 80.67 ft/s.
Distance equals rate times time, so in 5 seconds the car goes approximately 80.67*5 = 403.3 feet.
1 mile = 5280 feet1 hour = 3600 seconds1 mph = 1.4666 feet per second55 mph = 80.666666 feet per second10 seconds =>806.66 feet12 seconds => 968 feetSo, around 900 feet.
90 mph = 220 yards in 5 seconds.
4.5 seconds.
40 miles = 60 minutes. 40 / 360 * 13 = 1.444 where: 40 = miles, 360 = seconds in an hour, 13 = seconds. The car will travel approximately 1.4 km in 13 seconds.

No, the energy of a moving car is proportional to the square of its speed. So, a car traveling at 60 mph carries four times the energy as the same car traveling at 30 mph.
