He is 1.6 m now
1.6 m = 160 cm
He grew 10 cm every year, so before one year he is
(160 - 10) cm = 150 cm.
1.6 m = 160 cm
He grew 10 cm every year, so before one year he is
(160 - 10) cm = 150 cm.

Given,
Walt grew 10 cm in 1 year.
He is now 1.6 m tall.
To find,
His height before 1 year.
Solution,
Walt's height before 1 year would be 1.5 metres.
We can easily solve this problem by following the given steps.
According to the question,
Walt grew 10 cm in 1 year.
His present height = 1.6 m
His present height = (1.6 × 100) cm [ We have converted the units from metres to centimetres.]
His present height = 160 cm
His height before 1 year = His present height - the growth in his height in a one year
His height before 1 year = (160-10) cm
His height before 1 year = 150 cm
Now, converting the units from metres to centimetres,
1 m = 100 cm
1 cm = 1/100 m
Therefore, 150 cm = 150/100 m
150 cm = 1.5 m
Hence, Walt's height before 1 year was 1.5 metres.
