Bob can deliver his entire newspaper route in 7 hours. Jan can deliver the same newspaper route in 5 hours . How long would it take them to complete the route if they worked together
Answer provided by our tutors
Bobs rate per hour is 1/7 route per hour.
Jan's rate per hour is 1/5 route per hour.
Lat 'x' represent the number of hours that Bob and Jan need to finish the rate together.
The together rate of Bob and Jan is 1/x route per hour.
1/7 + 1/5 = 1/x
