Use the unit fractions 36in./1yd and 2.54 cm/1in. Convert 11 yd to cm.

1,005.84 cm

Step-by-step explanation:

Given the unit fractions, 36 in/1 yd (i.e. 36 inches = 1 yard), and 2.54 cm/1 in (i.e. 2.54 cm = 1 inches), to convert 11 yd to cm, first convert to inches, then convert what you have in inches to cm.

Thus:

Converting 11 yd to inches:

36 in = 1 yd

11 yd = 36*11 = 396 in

Converting 396 in to cm:

2.54 cm = 1 in

396 in = 2.54*396 = 1,005.84 cm

at an altitude of 1,500 feet.
