Amanda bikes 22 miles in 3 hours. Byron bikes three times farther than Amanda, in twice the amount of time.
What was Byron's average speed in miles per hour?
~~~~~~~~~~~~~~~~~~~~ 


According to the condition, Byron bikes three times farther than Amanda, which means he bikes 22 + 3*22 = 88 miles.


According to the condition, Byron bikes  3 hours * 2 = 6 hours.


The Byron's average speed is   =  =  miles per hour.    ANSWER




I understand that you expected to get another answer:   =  = 11 mph.


But this expectation is not correct, because in English "three times farther than" means "4 times as far as".



Obviously, you are a novice in this wording usage, but it is the English language feature, which is 

DISTINCT from the pattern of many other languages.

Ignore the answer and the solution by @josgarithmetic,  since they both are   T O T A L L Y   W R O N G.

It is the feature of this pseudo-tutor:  half of his  "solutions"  are wrong.
