Answer 1

Please recheck your arithmetic in your first problem. My answer is 10 minutes different than yours.

I agree with your second answer.

Answer 2

I get the same answer as melody on the first one, but please do check my arithmetic:

1/4 hr = 60 / 4 = 15 min
2/3 hr = 120 / 3 = 40 min
4/5 hr = 240 / 5 = 48 min

15 + 40 + 48 = 103 min = 1 hr 43 min

Answer 3

Thanks, Jim. I was wrong -- and you and Melody are correct.

Answer 4

After doing a dozen of these answers, I can barely remember that 2+2=5 :-)

Answer 5

<g> I like your sense of humor.
