12 minutes she wants to jump rope for 8 minutes and play and tag for 5 minutes will Tasha have enough time explain

Answers

Tasha wants to spend a total of 8+5 = 13 minutes playing. If she has only 12 minutes, she does not have enough time. (13 is more than 12)

She wants to play tag for 5 minutes and jump rope for 8 minutes. 5 minutes, plus 8 minutes, is 13 minutes, and 13 > 12 so therefore Tasha will not have enough time to play that much.
