Some kangaroos can jump over 30 feet in one jump! if a kangaroo could jump like that 150 times in the row, how much farther would it need to go to cover a mile?

The answer is 780 feet.

There is 5,280 feet in a mile. If the kangaroo jumps 30 feet 150 times, it will have gone 4,500 feet. So the kangaroo will need to go 780 feet to make a mile.

Formula: 5,280-4,500=780
