"world" power ???
Don't you mean "what is 7 to the 4th power?"
It's (7)(7)(7)(7) = (49)(49), or approx. 2,500. Multiply out 49(49) for the exact answer.
It would take them another 2.5 hours. To solve this you first need to multiply 60 by 4 to get 240. Subtract 240 from 780 to get 540. Then, Multiply 65 by 6 to get 390. Subtract 390 from the remaining 540 to get 150. Divide the final 150 by 60 to get 2.5. this is the remaining time they have to go before they reach their family and friends.
