please help!!the question is..at track practice,Sheila worked on the long jump.her first jump measured 3 yards,2 feet,8 inches.second jump measured 2 yards,1 foot,10 inches.How much longer was sheilas first jump than her second jump?express your answer in inches.And then what was the total length of her two jumps?express answer in feet.
3 yards,2 feet,8 inches = 140 inches
2 yards,1 foot,10 inches = 94 inches
46 inches
i got 144 not 140 for the first jump?
nvm i added 12 instead of 8
1) 108+12+8= 128
2) 72+12+10= 94
128-94=34
To find out how much longer Sheila's first jump was than her second jump, we need to subtract the length of the second jump from the length of the first jump, both measurements being converted to inches. Let's break down the calculations step by step:
First, let's convert the measurements to a common unit, which is inches:
- Sheila's first jump: 3 yards, 2 feet, 8 inches
To convert yards to inches, we know that 1 yard is equal to 36 inches. So, 3 yards would be 3 x 36 = 108 inches.
To convert feet to inches, we know that 1 foot is equal to 12 inches. So, 2 feet would be 2 x 12 = 24 inches.
Adding these up, the total inches for the first jump would be 108 + 24 + 8 = 140 inches.
- Sheila's second jump: 2 yards, 1 foot, 10 inches
Using the same conversion factors, we can determine that 2 yards is equal to 72 inches (2 x 36), 1 foot is equal to 12 inches, and 10 inches remain the same.
Adding these up, the total inches for the second jump would be 72 + 12 + 10 = 94 inches.
Now that we have the measurements in inches, we can calculate the difference between the first jump and the second jump:
First jump - Second jump = 140 inches - 94 inches = 46 inches
Therefore, Sheila's first jump was 46 inches longer than her second jump.
To find the total length of Sheila's two jumps in feet, we need to convert the total length from inches to feet:
First, add up the lengths of both jumps in inches (140 inches + 94 inches = 234 inches).
Next, since 1 foot is equal to 12 inches, we can divide the total length in inches by 12 to convert it to feet:
234 inches ÷ 12 = 19.5 feet
Therefore, the total length of Sheila's two jumps is 19.5 feet.
