Description: Sal solves a US customary distance word problem involving miles, yards, and feet. Created by Sal Khan and Monterey Institute for Technology and Education. If the distance around the field is 300 yards, how many complete laps would he need to do to run at least 2 miles? So they tell us how far one lap is, it's 300 yards, but we need to figure out how many laps to go 2 miles. We have distance here in terms of miles, we have it here in terms of yards.*Teacher Advisor is 100% free.
