Apilot flew a jet from city a to city b, a distance of 1700 miles. on the return trip, the average speed was 20% faster than the outbound speed. the round-trip took 5h 40 min. what was the speed from city a to city b?
mi/h

yes, gavin is right.

step-by-step explanation:

gavin is correct. 

this problem is about converting 9% per year to how many percent per quarter. the rate is still the same. it only differed in the time period. so, through dimensional analysis,

9% per year  × (1 year / 4 quarters) = 2.25% per quarter

if he was asked to convert 9% per year to how many percent per quarter  compounded quarterly, then you will not simply divide by four. this is because compounding is not linear.

hope this , have a good day. c;
