Question

Max can mow a lawn in 45 minutes. Jan takes twice as long to mow the same lawn. If they work together, how long will it take them to mow the lawn?

Answer 1

HELP ME PLEASE

Answer 2

1/45 + 1/90 = 1/x
Solve for x
Essentially, what you're doing is adding together their rates.
Max can mow "one lawn per 45 minutes"
Jan can mow "one lawn per 90 minutes"
To get their combined rate, just add them together: 1 lawn per x miuntes
