Dan takes 2 hours and 26 minutes to piece 2 jigsaw puzzles. How long will it take him to piece 7 jigsaw puzzles??

With solution (kung pano po nakuha yung sagot)


Sagot :

511 or 8 hrs. 31 min yung sagot.
2 hrs and 26min = 146 min.
146/2 = 73 per jigsaw
73 x 7 = 511 min or 8hrs and 31 min.

I already forgot what's the proper way in solving this. haha
Convert hours to minutes.
2 hrs. = 120 mins.
120 + 26 = 146 mins.
146 mins. : 2 jigsaw puzzles = n : 7 jigsaw puzzle

146 (7) = 1022
1022 ÷ 2 = 511

Therefore, the answer to your question is 511 mins or 8 hrs. and 31 mins.
