Ying Zyiyu covered the first 300 miles of a trip going at 60 mph and the last hundred going at 40 mph. What was his average speed for the entire trip?

65 PTS award guys?

The answer is 53 1/3

Step-by-step explanation:

how you do it is you first do 300/60=5

then you do 100/40=2.5

you add them to get 7.5

after then you do 400/7.5=53 1/3

that's the answer!

I hope you found this useful

(I submitted it onto the RSM page because I do RSM and it said it was correct. If it isn't then your thing has a problem)
