daniel walks at a speed 4 miles per hour. His mother walks at a speed 6 miles for per hour. Daniel left the house at 1pm. He wants to go to a playground which is exactly 2 miles away from his house.
He would arrive at 1:30 because if he walks at a speed of 4 miles an hour then it would take an hour for him to walk 4 miles. Half of 4 is two and half of an hour is 30
