Hi tutor, however the answer key shows 4.25m so I am sure how to obtain that answer...
Hu! Sorry, it’s my typo error as I wrote 32.5 instead of 35.5 m in my explanation.
So the revised working, just substitute 35.5 to 33.5m .
4u= 35.5-18.5 =17m
Hence, 1unit = 17/4 =4.25m
The model and method remains the same. Sorry for my typo and thanks for bringing this up! Hope that explains
