Caitlin goes for a 6 mile hike up a hill. She returns down by the same path. She walks uphill at an average speed of 2 miles per hour, and down the hill at an average of 4 miles per hour.What is Caitlin’s average speed (in miles per hour) for her whole hike?
Please give me answers quickly!
+36916 I am going to assume it is 6 miles ONE way (6 miles up a hill)
6 m / 2m/hr = 3 hrs
Down
6 m / 4 m/r = 1.5 hrs
total miles = 12 total time = 4.5 hrs
12 m / 4.5 hr = 2.67 m/hr
