A train travels 220 miles in 4 hours. What is the train's speed in feet per minute?
2 answers:
To work out speed you use the speed, distance and time formula: This is speed = distance/time.
You then need to convert the 220 miles into feet, you times the miles by 5280:
220 * 5280 = 1161600ft
Then you do hours into minuets, you times the hours by 60;
4 * 60 = 240mins
Then you place it into the formula:
1161600ft/240mins = 4840 ft/min
Hope this helps! :)
220 miles in 4 h = 55 mph multiply this by 5280 to get feet per hour then divide this by 60 to get ft/min
