Answer:
27 miles
Step-by-step explanation:
Find the rate or speed that Shawn hikes at. Find this reduced to lowest terms.
speed = distance / time
speed = 12 miles / 4h
speed = 3miles / h
Every hour, Shawn hikes 3 miles.
Multiply speed by time to find distance.
3mph X 9h = 27 miles
Therefore Shawn could hikes 27 miles in 9 hours.
