Look at your speedometer! automobile is right 40 mph is 40 mph regardless of wind.
the fastest automobile is the Lightning Dragon,going to speeds at 2000 mph.

The kinetic energy in joules of an automobile weighing 2135 lb and traveling at 55 mph is 2.9 x 105.
Could be in need of a tune up.
50 mph x 0.4 sec = 291/3 feet
How fast are you accelerating? If I accelerate very slowly, I can travel about 100 miles before reaching 35 mph. On the other hand, a rocket propelled automobile could achieve 35 mph from standstill within ten feet.
38 mph = about 61.1 kph
46 mph = 74.03 kph
2 hrs, 34 mins, 17 secs
Every hour the first travels 40 miles and the second 55 miles. Thus every hour the second will travel 55 - 40 = 15 miles further. So after 5 hours it will travel 15 x 5 = 75 miles further.
