45 miles x 55.5 cents / mile = 2497.5 cents
Stopping Distance = about 146.25 feet.
Just divide the distance by the speed.
666ft/45 X 60sec/1hr X 1mile/5280ft = 0.1682 miles/hr

1 minute 20 seconds.
At 45 mph it takes 1 minute 20 seconds to drive one mile.
80 mph
It will take 45 seconds.
45 seconds.
1 mile in 45 seconds is 80 mph. There are 60 seconds in a minute and 60 minutes in an hour; 60 * 60 = 3,600 seconds in an hour. 3,600 / 45 seconds = 80. And to cross-check: 80 mph * 5,280 feet in a mile = 422,400 feet per hour / 60 = 7,040 feet per minute / 60 = 117 1/3 feet per second * 45 seconds = 5,280 feet in 45 seconds.
45 mph (5280 feet/1 mile)(1 hour/3600 seconds) = 66 feet per second
It takes 45 seconds.
3 minutes and 45 seconds
Assuming the rate of 60 mph is constant, traveling 60 mph means you are traveling one mile per minute. Since 45 seconds is 3/4 of a minute, you have traveled 3/4 of a mile, or3,960 feet
At 60 mph you travel 1 mile per minute. At 80 mph it is 60/80 x 60 seconds = 45 seconds.
About 2 minutes and 40 seconds at 45 mph and about 1 minute and 50 seconds at 65 mph.
