He can mow 1/(x - 3) lawns per hour. You would more information to solve for x,
How much of the lawn per hour works out at 100/(x-3) % per hour
U know that Rudolph can mow 1000 square feet in 2 hours. You then know that he can mow 3000 square feet in 6 hours. From the given information, Rudolph can also mow 500 square feet in 1 hour. Therefore, Rudolph can mow 3500 square feet in 7 hours!

20ft. x 20ft.
If the lawn is twice as long as it is wide, and length times width is 288, then 3x = 288, or x = 96. The lawn is then 96 by 192 feet. This means that the perimeter is 576 feet (96 + 96 + 192 + 192).
Measuring a lawn Calculating the speed of a falling object
It takes person A 3 hours to do one lawn, thus in one hour they do one-third of a lawn. It takes person B 2 hours to do one lawn, thus in one hour they do one-half of a lawn. Together in one hour, they do 1/3 + 1/2 = 5/6 of a lawn; at this rate, it will take them 6/5 = 1.2 hours, or 1 hour and 12 minutes, to do one whole lawn together.
One hour twelve minutes.
one hour and 15 min! i think :)
Tom can mow 1,125 square ft of lawn in 1 hour.
The duration of Lawn Dogs is 1.68 hours.
You need to calculate what fraction of the total each mows in an hour, then add both up. The reciprocal of that number is the total time they would take - always assuming they continue working at the same rate.
2 hours
If 45 lawns can be done in 12 hours then 30 lawns can be done in 8 hours. This is a math problem.
x/4+x/7 (4x+7x) 11/28 It takes about 2.5 hours for them to mow the grass together.
Tractor 1 mows 25/4 acres per hour, tractor 2 mows 25/5 acres per hour, ie between them they can mow 6¼ + 5, 11¼ acres per hour so 25 acres will take 25/11¼ ie 2 and 7/9 hours.
