Respuesta :

Tina takes Karate classes every Tuesday and Thursday. The classes are 55 minutes long.

Take the 55 minutes and multiply that by 2 {2 represent Tuesday and Thurdsday} 55 x 2 = 110. Tina takes Karate classes for 110 minutes each week. Take the 110 and multiply that by 3 {3 represent the 3 weeks}. 110 x 3 = 330. 330 minutes is 5 hours and 30 minutes.

Tina's total hours of Karate in 3 weeks is 5 hours and 30 minutes.
1. 55 + 2(Tuesday and Thursday) 110 Tina takes it 3 weeks 110 times 3=330/60(hours) =5.5=5 hours and 30 minutes Hope this made sense and helped
