Loafu e le nngwe ya borotho kwa lebenkeleng la diborotho e ja R20. Befikela e nngwe e ja R10. Ke bokae di-loafu di le 3 tsa borotho di jang go feta di-befikela di le 2?

Carrie is planning the caroling schedule. The choir plans to sing "Deck the Halls" twice and "Jingle Bells" once. If "Deck the Halls" is 150 seconds long and "Jingle Bells" is 240 seconds long, how long will they be caroling?
Di-loafu di le 3 tsa borotho di ja 3 * R20 = R<<3*20=60>>60.
Di-befikela di le 2 di ja 2 * R10 = R<<2*10=20>>20.
Di-loafu tsa borotho di ja R60 - R20 = R<<60-20=40>>40 go feta di-befikela.
#### 40 

First find the total time the choir spends singing "Deck the Halls": 2 * 150 seconds = <<2*150=300>>300 seconds
Then add that time to the time spent singing "Jingle Bells": 300 seconds + 240 seconds = <<300+240=540>>540 seconds
#### 540
