contestants in a dance-a-thon rest for the same amount of time every hour. a couple rests for 49 minutes in 7 hours. how long did they rest in 8 hours?

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)

The answer is 225 miles per 4.5 hours. hope this ; )

The 3rd quadrant as 3x+g5ti=56i: 92d-543
