1 mile = 5280 feet 1hour = 3600 secs first convert mile to feet.. 155 miles = ? feet since there are 5280 feet in 1 mile...you will multiply 5280 feet by 155 miles to get the equivalent feet of 155 miles..that would give you 818,400 feet next you find how many seconds there are in your given hour. your given hour is 1 so multiply 3600 by 1 which gives you 3600 since you're looking for ft/s..divide your time by feet so... 818400/3600 = 227.33 ft/s
