660 feet. 75 mph /60 to get minutes which equals 1.25. They travel 1.25 miles every minute. To fond second you would do 1.25/60 since there are 60 seconds in a minute. You get 0.020... that’s how much of a mile they travel per second. Multiply by 6 to figure out how much of a mile within 6 seconds which is 0.125 miles (not feet). Then you convert this to feet. There are 5280 feet in a mile so you multiply that by the amount of miles which is 0.125 which equals 660 feet. They traveled 660 feet within those 6 seconds of sneezing and looking away from the road. Answer above almost got it but forgot to convert to feet.
