what is the answer to the problem below?
lauren and thomas stuffed envelopes for an election campaign. Lauren stuffed 56 envelopes in 5 minutes and thomas stuffed 42 envelopes in 3.5 minutes
.1) how many envelopes did lauren stuff per hour?
Lauren envelopes = 56/5 x 60 = 672 in an hour
2)how many envelopes did thomas stuf per hour?
Thomas envelopes = 42 / 3.5 x 60 = 720 in an hour
3)At the same rate of stuffing envlopes, aboubt how long will it take lauren and thomas, working together, to stuff a total of 2604 envelopes?
(56/5 + 42/3.5) Time(min) = 2604
56(3.5) + 42(5)] Time / (5)(3.5) = 2604
(196 + 210)Time = 2604 x 17.5
406 Time = 45570
Time = 45570 / 406
Time = 112.24 min
Time = 1 hour & 1 min & 75 sec ◄ Ans
