How long would it take Janet and Jim to shovel the driveway if they worked together? ____ minutes ??

- ALGEBRA -
**Reiny**, Wednesday, March 10, 2010 at 8:11amJanet's rate = DW/55

Jim's rate = DW/35

combined rate = DW/55 + DW/35 = 18DW/385

time working together = DW/(18DW/385)

= 385/18

= 21.39 minutes or 21 minutes 23 seconds
