Kennys lawn is 30 feet wide and 30 feet long. It takes him 1 hour to mow the lawn. If kenny mows at the same rate, about how many hours would it take him to mow a lawn that was 30 feet and 95 feet long?
30 * 30 = 900 square feet in one hour
30 * 95 = 2850 square feet
2850 / 900 = _______ hours
area of the 30by30 lawn = 900 ft^2
so he can mow 900 ft^2/hr
larger lawn has area of 2850 ft^2
time = 2850/900 hrs
= 3.166667 hrs
= 3 hours and 10 minutes
So confused I'm in 5th grade and my answer was 3hrs and 30 mins. Explain simple for me
2850/900 = 3 1/6
so that is 3 hours + 1/6 of an hour
1 hour = 60 minutes, so 1/6 of 60 = 10
(because 6x10 = 60)
To find out how many hours it would take Kenny to mow the larger lawn, we can compare the sizes of the two lawns and see the ratio of their lengths.
The area of the first lawn is calculated by multiplying the length by the width:
Area = Length × Width
Area = 30 feet × 30 feet
Area = 900 square feet
We know that Kenny can mow this lawn in 1 hour, so we can say that he mows at a rate of 900 square feet per hour.
Now let's compare the sizes of the two lawns. The length of the new lawn is 95 feet, which is more than three times the length of the first lawn (30 feet). The widths of the two lawns are the same (30 feet).
Since the length is more than three times larger, we can assume that it would take Kenny a proportionally longer amount of time to mow the larger lawn.
To estimate how many hours it would take, we can use the ratio of the length of the new lawn to the length of the first lawn:
95 feet ÷ 30 feet ≈ 3.17
So, it would take Kenny approximately 3.17 times longer to mow the larger lawn than the original one.
To find the estimated time, we multiply this ratio by the original time of 1 hour:
Estimated time = 1 hour × 3.17
Estimated time ≈ 3.17 hours
Therefore, it would take Kenny approximately 3.17 hours to mow a lawn that is 30 feet wide and 95 feet long, assuming he maintains the same mowing rate.
