Question

Joe's smartwatch can also measure the distance he swims. His target is to swim at least 1500 m every day. At the end of his day, his watch showed that he had swimmed a distance of 12 hectometer. Has Joe completed his target?

• A. Yes. Joe completed his target.
• B. No. Joe could not complete the target.
• C. It cannot be determined as units are different.

Answer 1

The correct option is B No. Joe could not complete the target.

Let's convert the covered distance to meters for comparison.

We know that each step is a multiple of 10.
Hectometer is 2 steps above meter.

$\therefore$ 1 Hectometer = $10\times 10$ Meters

$\Rightarrow$ 1 Hectometer = 100 Meters

$\Rightarrow 12\text{Hectometers}=12\times 100\text{m}=1200\text{m}$


$\therefore$ He covered 1200 m that day.

As 1500 m > 1200 m, therefore Joe did not completed his target.
