A cougar is sleeping for 4 hours at night, and a zebra for 2 hours more. How much time do both animals sleep in one week?
The zebra sleeps for 4 + 2 = <<4+2=6>>6 hours.
During one week, the cougar sleeps 4 * 7 = <<4*7=28>>28 hours.
And the zebra sleeps 6 * 7 = <<6*7=42>>42 hours.
Both animals sleep for 28 + 42 = <<28+42=70>>70 hours during one week.
