Answer 1

To determine the winner of the walking contest between Eva and Daniel, we first need to sum the total steps taken by each twin over the three days.

Eva's steps:

• Wednesday: 9,723
• Thursday: 11,095
• Friday: 10,345

Total steps for Eva: \[ 9,723 + 11,095 + 10,345 = 31,163 \text{ steps} \]

Daniel's steps:

• Wednesday: 12,170
• Thursday: 8,230
• Friday: 10,770

Total steps for Daniel: \[ 12,170 + 8,230 + 10,770 = 31,170 \text{ steps} \]

Now compare the totals:

• Eva: 31,163 steps
• Daniel: 31,170 steps

Now we find out who won and by how many steps: Daniel won the contest.

To calculate how many more steps Daniel took than Eva: \[ 31,170 - 31,163 = 7 \text{ steps} \]

So, Daniel won the contest by taking 7 more steps than Eva.
