***
Candy can deliver all the papers in 95 min
1/95=Her work rate
Tim can deliver all the papers in 55 min
1/55=His work rate
Working together they can deliver all the papers in x min
1/x=Their work rate
sum of indv. work rates=work rate working together
1%2F95%2B1%2F55=1%2Fx
lcd:x*95*55
55x+95x=95*55
150x=5225
x=34.83
How long does it take the two when they work together? 34.83 min
