Question

Jacob left Darryl's house and drove toward

the recycling plant. Jessica left one hour
later driving at 30 mph in an effort to
catch up to Jacob. After driving for two
hours Jessica finally caught up. What was
Jacob's average speed?

Answer 1

Jacob's average speed is 30 mph.

Step-by-step explanation:

To find Jacob's average speed, we can use the formula:

Average Speed = Total Distance / Total Time

Given that Jessica caught up to Jacob after driving for 2 hours, we know that Jacob also drove for 2 hours. Let's assume the distance Jacob drove is 'D'.

Since Jessica's speed is 30 mph, she traveled a distance of 30 mph x 2 hours = 60 miles. And since she caught up to Jacob at that point, it means Jacob had also covered the same distance of 60 miles in 2 hours.

Therefore, Jacob's average speed is 60 miles / 2 hours = 30 mph.
