Answer:

b. 25,700

Step-by-step explanation:

.88 - .623 equals 257

257 × 100 ( 1 m to cm) equals 25,700

Answer:

To convert kilometers into centimeters first, you need to multiply by 100,000.

So, 0.623 x 100,000 = 62,300

And 0.88 x 100,000 = 88,000

As the problem is asking what is the difference between the distances they walked in terms of using the cm measurement, subtract 88,000 and 62,300.

88,000 - 62,300 = 25,700 cm.

Therefore, the answer is letter B.
