if he walked 20 miles in 5 hours, then how many miles did he walk in 1 hour?
OpenStudy (briyanna12):
5 miles or.......4?
jimthompson5910 (jim_thompson5910):
20/5 = 4 miles
jimthompson5910 (jim_thompson5910):
20 miles in 5 hours means he walks 4 miles in 1 hour
OpenStudy (briyanna12):
yeah thats what i thought cause 20 divided by 5=4 thx:)))
