Question

The distance from city A to city B and from city B and city C is represented below.


The total distance between city A and C is metres.

• A. 12,000
• B. 20,000
• C. 10,200
• D. 10,020

Answer 1

The correct option is C 10,200

$\text{The distance from city A to city B}$ $\text{= 10 km}$
$\text{The distance from city B to city C}$ $\text{= 200 m}$

$\text{To calculate the total distance}$ $\text{between the city A}$ $\text{and city C,}$ $\text{we have to add the distances}$ $\text{from city A to B and from city B}$ $\text{to C.}$

$\text{So, let's convert the distances into}$ $\text{same units of measurement.}$

$\text{As we know that,}$
$\text{1 kilometer (km) = 1,000 meter (m)}$

$\text{Hence, we will multiply 10 with 1,000.}$

$⟹\text{10}\times 1,000\text{= 10,000}$

$\text{So, the distance between city A and B}$ $\text{= 10,000 m}$

$\text{Now, let's calculate the total distance}$ $\text{from A to C.}$

$⟹\text{10,000 + 200 = 10,200 m}$

$\text{Thus, the total distance between}$ $\text{the city A and B}$ $\text{is 10,200 meters.}$
