â How tall is the fox?
Donât just guess! Take a moment and try to solve it yourself before reading the answer.
Let the height of the rock be R and the height of the fox be F.
From the first image:
R â F = 100 cm
From the second image:
R + F = 160 cm
Now add the two equations together:
(R â F) + (R + F) = 100 + 160
The foxâs height cancels out:
2R = 260
So:
R = 130 cm
Now go back to the first measurement:
130 â F = 100
Therefore:
F = 30 cm
â FINAL ANSWER: THE FOX IS 30 CM TALL. đŠ
Were you able to get 30 cm before seeing the solution?
A lot of people instinctively answer 60 cm because they focus on the difference between 160 and 100, but that 60 cm represents twice the foxâs height, not the foxâs height itself.
If you got it right, your observation and algebra skills are on point! đ§ đ„
