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.
How long would it take a car traveling 60 miles an hour to go 270 miles? 60(hour)+60(hour)=120(2 hours)+60(hour)+60(hour)=240(4hours+30=270(4hours and 30 min)You have 4 hours and 30 minutes of a drive if some body is driving 60 miles an hour.t 120 mph, it takes 30 minutes.   At 60 mph, it takes one hour.   At 30 mph, it takes two hours.   If the train keeps changing speed, you have a more difficult calcu â¦ lation.
