Question

If an Olympic athlete misses out on a gold medal by $1.2\text{cm}$ in the long jump. The distance he/she misses (in inches) is.

• A. 0.468
• B. 4.68
• C. 0.486

Answer 1

The correct option is A 0.468

Note:
$1\text{cm}=0.39\text{in}$

So,
$1.2\text{cm}=0.39\times 1.2\text{in}$
To get the product of 0.39 and 1.2, first find the product of 39 and 12.

$\Rightarrow 39\times 12=468$
There are 2 decimal places in 0.39 and one in 1.2. So, to find the product of $0.39\times 1.2$, we will have three decimal places in the product.
$\Rightarrow 0.39\times 1.2=0.468\text{in}$
Answer:
So, he/she misses by 0.468 inches in long jump.
