.
Each person takes 1 truck and takes five hours to load,
so 1 truck takes 5 person hours. 5 person hours/2 people=2.5 hours

Rate, Time, Job
RT=J

5r%2A5=5, if one truck is one job.
r=1%2F5; r is the one-person rate.

Can you do the question part?

Two people to load 1 truck,
2r%2At=1, t being time to do this job
t=1%2F%282r%29
t=1%2F%282%281%2F5%29%29
t=5%2F2=highlight%282%261%2F2%29
