How far does a car travel in 5 sec going 45 mph?

To find out how far a car travels in 5 seconds at 45 mph, first convert the speed to feet per second. Since 1 mile is 5,280 feet and there are 3,600 seconds in an hour, 45 mph is approximately 66 feet per second. Therefore, in 5 seconds, the car would travel about 330 feet (66 feet/second × 5 seconds).
