sue can complete an order in 5 hours. Felipe can complete the same order in 6 hours. IF they work together how long would it take them to complete the order?
Answer provided by our tutors
let
x = the hours they need to complete the order together
the together rate: they will complete 1/x order in 1 hour
Sue's rate is: 1/5 order in 1 hour
Felipe's rate is: 1/6 order in 1 hour
1/5 + 1/6 = 1/x
by solving we find:
x = 30/11 hr
x = 3 8/11 hr
x = 3 hr 8*60/11 min
x = 3 hr 44 min approximately
