Charlie can make 5350 steps while running on a 3-kilometer running field. If he can run around the field 2 1/2 times during a running session, how many steps was he able to make? Let's answer step by step:
Charlie's steps for 3 kilometers is 5350 x 2 = 10700 steps were made when he run twice the field. Since he has run half of the field 5350 / 2 = 2675 steps were made when he runs half of the 3 - kilometer field. Therefore, Charlie was able to make 10700 + 2675 = 13375 steps for the 2 and a half run around the field. The answer: 13375.
