Explanation
To find the difference between 100 metres and 100 yards, we first convert yards to metres.
One yard is exactly 0.9144 metres.
Therefore, 100 yards is equal to 100 multiplied by 0.9144, which equals 91.44 metres.
To find how much longer 100 metres is, we subtract the distance of 100 yards in metres from 100 metres.
100 metres minus 91.44 metres equals 8.56 metres.
This confirms that 100 metres is 8.56 metres longer than 100 yards, making option B the correct answer.
