You and your friend race from point A to point C . You run from A to B and then from B to C . Your friend runs from A to D and then from D to C . You run at an average rate of 7.8 miles per hour and your friend runs at an average rate of 8.1 miles per hour. Is it possible to determine who wins the race?

Explanation:

Looking at the image, if both friends had ran at the same speed rate, the match would've ended as a draw. However, my friend had ran faster than I did, therefore, my friend would've won the race due to speed.

Hoped this helped.

-362

step-by-step explanation:

(12)(4)+2(12)-34(12)+2(12)-3

  \/         \/         \/         \/

  48 +   24 -   408 + 24 - 3

      \   /               \   /

          72     -     432 - 3 = -363

it would open into a square depending on the type of envelope i’m not sure about the second part
