Answer:
Two more people.
Step-by-step explanation:
If 4 people can mow a lawn in 6 hours, then 4 people can mow 1/6 of a lawn in 1 hour.
If 4 people can mow 1/6 of a lawn in 1 hour, then 1 person can mow 1/24 of a lawn in 1 hour.
If 1 person can mow 1/24 of a lawn in 1 hour, then 6 people can mow 1/4 of a lawn in 1 hour.
If 6 people can mow 1/4 of a lawn in 1 hour, then 6 people can mow a lawn in 4 hours.
6 people minus 4 people is 2 people.
There are two more people will be needed to mow the lawn in 4 hours, It is assuming that each person mows at the same rate
What is the rate of doing work?
The rate of work is defined as the number of units of work completed per unit time.
Let the number of the person are x,
Condition 1;
4 people in 6 hours complete the work, work done in one hour;
1 hour =(1/6) of the total work
Condition 2;
If four individuals can do one-sixth of the total work, one person can do one-quarter of the work in an hour.
1 person do = (1/4) of the total work;
Condition 3;
If one person can do 1/24 of total work
Six persons can do 1/4 of total work in the same amount of time.
If six individuals can mow a quarter of a lawn in an hour, The number of people will be needed to mow the lawn in 4 hours;
n=6-4
n=2
Hence, there are two more people will be needed to mow the lawn in 4 hours,
