Answer 1

$\large{\underline{\textsf{\textbf{ Given \: Information: }}}}$

• The distance from City A to City B is 586 km 85 m.

• City C is on the way between City A and City C.

• The distance from City A to City C is 8 km 75 m.

$\large{\underline{\textsf{\textbf{ To \: calculate : }}}}$

• How far is City C from City B i.e, we have to find the distance from City C to City B.

$\large{\underline{\textsf{\textbf{ Calculation :}}}}$

Let the distance from City C to City B be x.

● Distance from City A to City B = 586 km 85 m

• 1 km = 1000 m

→ Distance from City A to B = (586 × 1000) m + 85m

→ Distance from City A to B = 586000 m + 85 m

→ Distance from City A to B = 586085 m

Also,

● Distance from City A to City C = 8 km 75 m

• 1 km = 1000 m

→ Distance from City A to C = (8 × 1000) m + 75m

→ Distance from City A to C = 8000 m + 75 m

→ Distance from City A to C = 8075 m

According to the question,

• City C lies between City A and B. So,

→ Distance from A to C + Distance from B to C = Distance from A to B

→ 8075 m + x = 586085 m

→ x = 586085 m - 8075 m

→ x = 578010 m

Converting into kilometre :

→ 1000 m = 1 km

→ 578010 m = 578 km 10 m

Therefore,

• City C is 578 km 10 m far from City B .
