WILL MARK BRAINLIEST! PLS HELP! A cyclist travels at 20 kilometers per hour when cycling uphill, 24 kilometers per hour when cycling on flat ground, and 30 kilometers per hour when cycling downhill. On a sunny day, they cycle the hilly road from Aopslandia to Beast Island before turning around and cycling back to Aopslandia. What was their average speed during the entire round trip?

Answer: 25km/h

Step-by-step explanation:

Theyre going to Beast Island which is said to be hilly. We can say their average speed is 20km/h. They are also returning which means they are now going downhill. The rate for going downhill was said to be 30km/h. The average between any two things is adding their value and dividing by 2

20 + 30 = 50

50/2 = 25
