Question

Henry covers a total distance of 1245 km from city A to city C through city B. If the distance from city A to city B is 456.4 km, find the distance between city B and city C. Express the answer as a decimal.​

Answer 1

Answer:

Given that the distance between City A and City B is 6 cm and that 1 cm on map represents 200 km

Using unitary method,

If 1 cm→200 km

then, 6 cm→200×6 km

⇒1200 km

We know that, 1 km=1000 m

∴ 1200 km=1200×1000 m

⇒1200000 m

Hence, the actual distance between City A and City B is 1200000 m

Answer 2

Answer:

1245 km-456.4 km=788.6

Step-by-step explanation:

1245 km-456.4=?

1245 km-456.4=788.6
