Question

A snail crawled up a tree that is $1,200$ cm high in a day. How many cm did it crawl in an hour?

• A. $50$
• B. $120$
• C. $240$
• D. $12$

Answer 1

The correct option is A $50$

Height covered in a day $=1,200\text{cm}$

$\because 1\text{day}=24\text{hours}$

So, height covered in an hour
$=\frac{1,200}{24}\text{cm}$
$=\frac{24\times 5\times 10}{24}\text{cm}$
(cancelling 24 from numerator and denominator)
$=5\times 10\text{cm}$
$=50\text{cm}$

Hence, Snail crawled up 50 cm in an hour.
