Question

Sloan the sloth crawls at $100$ meters per hour when crawling uphill, $120$ meters per hour when crawling across flat ground, and $150$ meters per hour when crawling downhill. One day, Sloan crawls across the forest floor from a tree stump to a spring, and then takes the same route in reverse to return to the tree stump. What was Sloan's average speed during the entire round trip?

Answer 1

Answer:

246.6 meters per hour

Step-by-step explanation:

Step one:

Speed uphill 100meters per hour

Speed on flat ground 120 meters per hour

Speed uphill  150 meters per hour.

Required

The average speed.

Step two:

To get the average speed, let us add all the individual speeds and divide by 3(three different speeds), then multiply the result by 2(the return trip)

Average speed= (100+120+150)*2/3

Average speed= 740/3

Average speed=  246.6 meters per hour
