200 ft in 15 seconds ~= 13.333 ft/s
13.333 ft/s * 3600 s/hr / 5280 mi/ft ~= 9.091 mph
That depends on how fast the truck is traveling.
1 second if you are traveling 15 feet.
~3 seconds
68.2 miles per hour.
Stopping distances are measured in feet not in seconds. At 40 mph you're traveling 58.7 feet per second. The average driver reaction time is about 3/4 second which equates to 44 feet. After applying the brakes it will take approximately 82 feet to stop the vehicle. The total stopping distance for a car traveling 40 mph will be 126 feet when you include reaction time and actual stopping distance of the vehicle. If you divide 126' x 58.7' which is the distance traveled per second you get 2.14 seconds. This is assuming you're paying attention and have average reaction time while driving.
4,950 feet.
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
You are traveling 70.18 feet every 1.1 seconds at 43.5 mph
200 feet
YES. At 55 miles per hour you are traveling at 80.67 feet every second. This means that every 15 seconds you are traveling 1,210.05 feet.
1,531.2 feet in 12 seconds @87 mph
That depends on how fast the truck is traveling.
4.5 feet in 188 seconds is only 0.0163 mph
Multiply by 20 to get how far is traveled in a minute, which gets 1210 feet per minute. Then multiply by 60 to get how far is traveled in an hour, which gets 72600 feet per hour. Divide by 5280 to convert feet to miles, which gets 13.75 miles per hour.
300 feet every 5 seconds equates to 40.9 mph
Since one hour is 3600 seconds (60 minutes per hour times 60 seconds per minute), 12 seconds is 12 over 3600th of an hour, or 0.03333 of an hour. In 12 seconds, at 495360 feet per hour, you would travel about 1651 (495360 times 12 divided by 3600) feet.
87 miles per hour = 1,531.2 feet per 12 seconds
