Answer:
56 cm
Step-by-step explanation:
Here's what the question is asking for.
150 ≤ 1.25h ≤ 220
120 ≤ h ≤ 176 . . . . the range of heights that can use the skis
176 -120 = 56 cm . . . . the difference in heights
__
Here's an easier way to calculate it.
220/1.25 -150/1.25 = (220 -150)/1.25 = 70/1.25 = 56
The height difference is 56 cm.
_____
We judge one subtraction and one division to be easier and less error-prone than two divisions and a subtraction.
