Amiri can deliver his newspapers in 86 minutes.
It takes Horus 64 minutes to do the same route.
How long would it take them to deliver the newspapers if they work​ together?
:
let t = the time required when working together
let the complete job = 1
t%2F86 + t%2F64 = 1
Use the least common multiple of 86 and 64, multiply the equation by 2752
2752*t%2F86 + 2752*t%2F64 = 2752
cancel the denominator
32t + 43t = 2752
75t = 2752
t = 2752/75
t = 36.693 minutes, working together
