Answer:
4 hours
Step-by-step explanation:
first you find out how much 3/4 of a mile is in 9 miles
1/4 = .75
9 divided by .75 = 12
So it takes 12 of 3/4 of a mile to go to 9 miles
Then multiply 12 by 1/3 to find he time since it takes 1/3 of an hour to travel 3/4
12 * 1/3 = 4
So it will take Mt Gregg 4 hours to travel 9 miles
