Question

3. It took Ellie 4 hours to paddle her canoe 10 km upstream. After a
leisurely 3 hour picnic, she paddled home in 1 hour.
A) How fast did Ellie paddle upstream?
B.) What was Ellie's average speed while paddling?​

Answer 1

Answer: A) 2.5 km/ hour

You divide 10/4 and get 2.5, so 2.5km an hour.

B) 6.25 km/ hour

You have 2.5km/ hour plus 10km/ hour OVER 2. This would equal 12.5 km over 2

You then get 6.25 from doing 12.5/2
