The time required to do a job varies inversely as the number of people working on it, it takes five hours for seven volunteers to pick up the rubbish from 1 mile away. how long will it take 10 volunteers to complete the job

3.5 hours

Step-by-step explanation:

let t represent time and n the number of volunteers.

Given that t varies inversely as n then the equation relating them is

t = ← k is the constant of variation

To find k use the condition t = 5 when n = 7, then

k = tn = 5 × 7 = 35, thus

t = ← equation of variation

When n = 10, then

t = = 3.5 hours
