Hello!
As this exercise informs the approximate heights, you can consider just this value (don't need to write two heights in this case).
To make this chart, I used the heigths:
• Mercedario: 6770m
,
• Misti, Volcán: 5820m
,
• Pular: 6230m
,
• Sajama: 6520m
,
• Talima: 5220m
Look at the chart below:
