The height of four friends are given in different units below

The height of four friends are given in different units below. Which height is the tallest? A. 5 it. & 7 inches B. 1.7 meters C. 68 inches D. 1.71 meters

The Correct Answer and Explanation is:

Let’s convert all the given heights to the same unit, such as inches, so we can compare them easily.

1. 5 ft. & 7 inches:
   • First, convert 5 feet to inches:
     5 ft = 5 × 12 = 60 inches.
   • Then, add the 7 inches:
     60 inches + 7 inches = 67 inches.
2. 1.7 meters:
   • 1 meter = 39.37 inches, so:
     1.7 meters = 1.7 × 39.37 = 66.93 inches.
3. 68 inches:
   • This is already in inches, so it’s 68 inches.
4. 1.71 meters:
   • 1 meter = 39.37 inches, so:
     1.71 meters = 1.71 × 39.37 = 67.32 inches.

Comparison of Heights in Inches:

• 5 ft. 7 inches = 67 inches
• 1.7 meters = 66.93 inches
• 68 inches = 68 inches
• 1.71 meters = 67.32 inches

The tallest height is 68 inches, which corresponds to option C.

So, option C (68 inches) is the correct answer.
