Help Needed:
Eduardo’s average speed on his commute to work was 55 miles per hour. On the way home, he hit traffic and only averaged 40 miles per hour. If the round trip took him 1.25 hours, which expression represents the distance, in miles, for his trip home that is missing from the table?

Best ResponseYou've already chosen the best response.0given  55 mph to commute to work 40 mph to commute to home a round trip is 1.25 hours

Best ResponseYou've already chosen the best response.0so what happened to the speed? @Roman532

Best ResponseYou've already chosen the best response.0yes it decreased due to traffic... is the math symbol for decrease + or ?

Best ResponseYou've already chosen the best response.0yes because decrease means going down.. decrease in speed means going slow

Best ResponseYou've already chosen the best response.0the formula is distance = rate x time

Best ResponseYou've already chosen the best response.0we are given that the rate to commute to home is is 40 distance =40 x ?

Best ResponseYou've already chosen the best response.0So I'm guessing that narrows it to C or D?

Best ResponseYou've already chosen the best response.0yeah... I'm thinking that the variable for time goes first what happened to the time? If it took 1.25 and speed went down from 55 mph to 40 mph...

Best ResponseYou've already chosen the best response.0He hit traffic... And I'm guessing the answer is D?

Best ResponseYou've already chosen the best response.0so our time has to be t1.25 because he hit traffic and his speed decreased

Best ResponseYou've already chosen the best response.0distance = rate x time distance = 40 (t1.25)

Best ResponseYou've already chosen the best response.0the reason why it's not the first two choices is that it neglected the rate

Best ResponseYou've already chosen the best response.0Right because it has to be rate x time

Best ResponseYou've already chosen the best response.0not sure if order matters.. I'm assuming the variable goes first.. it's been over a decade since I've done those problems and I end up just guessing when I first did them... but I read it through carefully finding out what's given and what do I need to translate in math terms

Best ResponseYou've already chosen the best response.0yeah I'm having a hard time deciding whether it's C or D

Best ResponseYou've already chosen the best response.0I get 3 tries, 2 left. It's a quiz I must pass. I'm going with C because it makes sense to x 40 and 1.25 and then subtract the hours

Best ResponseYou've already chosen the best response.0Haha I just hate Algebra and Calculus, I'm not going to be some rocket scientist when older so I really do not need it, basically pointless. Busy work.

Best ResponseYou've already chosen the best response.0:S I'm looking at similar examples... the variable does go first.
