Question 133768
A man walks at a pace of 3 miles per hour. After 2 hours he stops for a rest. Let t be time AFTER the rest. Let d be the TOTAL distance traveled since he started. Write an equation linking d and t. Explain what you did to get your answer.
:
The dist walked before his rest: 2 hrs at 3 mph
2*3 = 6 mi before the rest
:
The dist walked after the rest: t hrs at 3 mph
3t = dist after the rest
:
Total dist = dist after rest plus dist before rest
d = 3t + 6
