Question

<!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> Ruby cycles for 3 km 440 m each day. How many meters does she cycle in 10 days?

• A. 30,400 m
• B. 34,400 m
• C. 34,000 m
• D. 44,400 m

Answer 1

The correct option is B 34,400 m

Distance traveled by Ruby in one day
= 3 km 440 m

Let's convert the distance into meters.

The conversion table is represented as:

So, 1 km = 10 × 10 × 10 = 1,000 m
And, 3 km = 3,000 m

Distance traveled by Ruby in one day
$=$ 3 km 440 m
$=$ (3 × 1000) m + 440m
$=$ 3000 m + 440 m
$=$ 3,440 m

$\text{∴ In one day, Ruby travels 3,440 m.}$
$\text{In 10 days, the distance Ruby will travel}$
$\text{= 10}\times \text{3,440 = 34,400 m}$
