Loretta and Dolly can tile a bathroom in 8 hours Working alone it takes Dolly 4 hours and 40 minutes longer than Loretta to tile this bathroom How long would it take for Loretta to tile the bathro?

Answer 1

Equation 1: L+D=(8x60) L+D=480

D=480-L

Equation 2:

D=L+((4x60)+40)

D=L+(280)

480-L=L+280

-280 -280

200-L=L

+L +L

2000=2L

----- ------

2 2

100=L

D=480-L

D=480-100

D=380

it takes L 100 minutes and D 380 minutes

it takes L 1hr 40min and D 6 hr 20 min.
