Answer: They hike 30 miles and 20 miles in 1 hour respectively and they hike 60 miles and 40 miles in 2 hours respectively.

Step-by-step explanation:

Since we have given that

Number of mile Jeff hikes in every 15 minutes = \(\dfrac{1}{2}\)

As we know that

1 hour = 60 minutes

So, number of mile Jeff hikes in every 1 hour = \(\dfrac{1}{2}\times 60=30\ miles\)

number of miles Jeff hikes in every 2 hours = \(30\times 2=60\ miles\)

Number of miles Lisa hikes in every 10 minutes = \(\dfrac{1}{3}\)

Number of miles Lisa hikes in every 1 hour = \(\dfrac{1}{3}\times 60=20\ miles\)

Number of miles Lisa hikes in every 2 hours = \(20\times 2=40\ miles\)

Hence, they hike 30 miles and 20 miles in 1 hour respectively and they hike 60 miles and 40 miles in 2 hours respectively.
