Your younger brother is pulling a sled up a hill. Each minute he moves foward 20 feet but also slides back 3 feet. Describe how you can determine the time he needs to pull his sled 130 feet foward.
130/17 = ?
i don't know the answer. please helpme
is this the correct answer?
To determine the time it takes for your younger brother to pull his sled 130 feet forward, we need to calculate the total distance he covers in each minute and find the number of minutes it takes to cover 130 feet.
1. First, let's determine the distance covered in each minute. Your brother moves forward 20 feet but also slides back 3 feet, so his net progress in each minute is 20 feet - 3 feet = 17 feet.
2. Next, we need to calculate the number of minutes it takes for your brother to cover 130 feet. We can do this by dividing the total distance (130 feet) by the net progress in each minute (17 feet).
130 feet / 17 feet = 7.65 minutes
Since time cannot be expressed in decimals, we need to round up the value.
3. Rounding up, we find that it takes approximately 8 minutes for your brother to pull his sled 130 feet forward.
Therefore, your younger brother needs approximately 8 minutes to pull his sled 130 feet forward.
