If a car is traveling 40 mph what distance will it cover in 30 mins?
40 mph = 40 miles in 60 minutes = 20 miles in 30 minutes.
What is the average speed of a car that traveled 200.0 miles in 5.0 hours?
Just divide the distance by the speed.
How many seconds will it take for a car to stop if it is traveling at a speed of 40 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.
How much time will you save by traveling 4.5 miles at 50 mph instead of 40 mph?
Distance = Rate * Time or, for our purpose Time = Distance/Rate at 50 mph Time = 4.5 miles/50 mph = 0.09 hours = 5.4 minutes ----------------------------- at 40 mph Time = 4.5 miles/40 mph = 0.1125 hours = 6.75 minutes ---------------------------------------------------- 6.75 - 5.4 = 1.35 minutes saved
How long would it take to travel 2983 miles at a travelling speed of 1850 MPH?
Approximately 1 hour 40 minutes
