Question

Every day, Jason runs for 36 minutes and lifts weights for 44 minutes. How many minutes will Jason spend working out in 8 days?

Answer 1

36+44=80
80 x 8 = (8 x 10) x 8
8 x 8 = 64
64 x 10 =640
He will workout for 640 hours over a period of 8 days.

Answer 2

36 x 8 = 288
44 x 8 = 352
288 + 352 = 640
So 640 minutes in 8 days.
