Calculating Real Distances Using Scale

In this video tutorial, David, a geography teacher, explains how to calculate real distances using different map scales. The lesson covers three examples: a map of Brazil, a map of São Paulo, and a graphic scale. Each example demonstrates how to convert map measurements into real-world distances by applying the appropriate scale conversion. The video concludes with a call to action for viewers to like and subscribe to the channel.

What is the main topic of today's lesson?

• Learning about different countries

• Multiply by 50

What is the real distance if the map distance is 72 cm in the first example?

• 36,000 km

• 360 km

• 36 km

• 3,600 km

In the second example, what is the scale of the map of São Paulo?

• 1 cm equals 6,500 km

• 1 cm equals 650,000 cm

• 1 cm equals 65 km

• 1 cm equals 6,500,000 cm

What is the real distance between Campinas and São Paulo if the map distance is 1.6 cm?

• 1.04 km

• 10.4 km
