John is 4 feet 8 inches tall. His older brother, mark, is 6 feet 4 inches tall. How much taller is mark than John? 2 feet 4 inches, 1 foot 8 inches, 2 feet 8 inches, or 1 foot 2 inches
To calculate the height difference between Mark and John, we need to convert their heights to the same unit of measurement.
Since there are 12 inches in 1 foot, we can convert John's height to inches by multiplying 4 feet by 12 and adding the 8 inches.
This gives us 4*12 + 8 = 48 inches.
Mark's height is already given in inches as 6 feet 4 inches, which is 6*12 + 4 = 76 inches.
Therefore, Mark is 76 - 48 = 28 inches taller than John.
Since there are 12 inches in 1 foot, we can divide 28 inches by 12 to get a measurement in feet.
This gives us 28 / 12 = 2 feet and a remainder of 4 inches.
Therefore, Mark is 2 feet 4 inches taller than John.
The correct answer is 2 feet 4 inches.
