Question

Any ideas about this one? The answers I got have not worked:

4
1
2
h more than Irene to do the job. How long does it take each person working alone to wash all the windows?

Answer 1

it takes him 4 1/2 more hours

Answer 2

you are familiar with the formula \[\large \frac{t}{x} + \frac{t}{y} = 1\] where t = total time working together

Answer 3

I've done this problem but I cannot get the correct answer. I've been on this problem for a long time

Answer 4

convert 5 h 52 mins and 4 1/2 hours into minutes first what do you have?

Answer 5

352/60 and 270/60

Answer 6

why is there over 60? no over 60..

Answer 7

so total time = 352 minutes

let x = Irene's time
Henry = 270 + x

can you do the equation now?

Answer 8

henry is 82 mins

Answer 9

uhh no...you cannot just simply subtract 270 from 352..do the equation

Answer 10

\[\large \frac{t}{x} + \frac{t}{y} = 1\]
