Answer :
To find out how many minutes it will take Teddy to cut all the grass on the school field, we can follow these steps:
1. Determine the area of the field:
- The field is a rectangle with a length of 100 meters and a width of 80 meters.
- To find the area of a rectangle, multiply its length by its width.
- Area = Length × Width = 100 m × 80 m = 8000 square meters.
2. Understand Teddy's cutting rate:
- Teddy cuts 40 square meters of grass per minute.
3. Calculate the total time needed:
- To find out how long it will take to cut the entire area, divide the total area by the cutting rate.
- Time = Total Area / Cutting Rate = 8000 square meters / 40 square meters per minute = 200 minutes.
Therefore, it will take Teddy 200 minutes to cut all the grass on the field.
