12. It takes James 20 minutes to ride his bike to the lake by one path, and
30 minutes to come back by a different path. If he goes to the lake and
back 4 times, how many minutes does he spend riding? Which gives the
answer? *
O (8+20) x (8+30) = 28 x 38 = 1,064 minutes
О
8 x 20 x 30 = 4,800 minutes
О
(8+8) X (20+30) = 16 x 50 = 800 minutes
O (8x20) + (8x30) = 160 + 240 = 400 minutes
