This is a rate problem
Terry's rate of painting is ( 1 house)/(4 hrs)
Nissi's rate of painting is (1 house)/(6 hrs)
Let = the time it takes them to paint the
house working together
Just add their rates to get their rate working together

Multiply both sides by

Their rate working together is (1 house)/(2.4 hrs)
To convert hrs to minutes:
hrs x min/hr = min
It takes them 2 hours and 24 minutes working together
