Cecily is swinging. The swing goes back and forth twice every five seconds. How many seconds does it take her to go back and forth one hundred times? About how many minutes is that?

Please help me.

2 times/5 sec = 100 times/x sec
2/5 = 100/x
2x = 500
x = 250

it would take 250 seconds, you tell me how many minutes that is ...

btw, I just noticed you already posted this and it was answered.

250
250 seconds. So 4.17 mins. On my worksheet, it has selections: 3 1/2 mins, 4 mins, and 4 1/2 mins. If u have choices like these it’s probs 4 1/2 sry if I’m wrong.
