Tim left the city for vacation.
Dan left 7 hours later going 67 mph faster to catch up.
After 6 hours Dan caught up.
What was Tim's average speed
:
Let s = Tim's average speed
:
We know from the information, that Tim's travel time was 13 hrs and Dan's travel time was 6 hrs.
When Dan catches Tim, they will have traveled the same distance
Write distance equation; dist = time * speed
:
13s = 6 * 67
13s = 402
s = 402/13
s = 30.923 ~ 31 mph is Tim's av speed
