Answer:
Tara will have to travel ≅ (approximately) 2,475 km from Manaus to Sao Paulo and ≅ 495 km from Sao Paulo to Belo Horizonte, using the ruler and the map scale given.
Step-by-step explanation:
1. Using the ruler, we have:
a. The distance from Manaus to Sao Paulo is ≅ 9 cm.
b. The distance from Sao Paulo to Belo Horizonte is ≅ 1.8 cm.
2. Now using the scale of the map provided for calculating the real distance, we have:
a. 9 cm * 27'500,000 = 247'500,000 cm
Converting that amount to meters we have:
1 meter = 100 cm, thus:
247'500,000/100 = 2'475,000 meters but it's still too big to handle. Let's convert meters to kilometers, this way:
1 kilometer = 1,000 meters, thus:
2'475,000/1,000 = 2,475 km
The real distance from Manaus to Sao Paulo using the scale is ≅ 2,475 km (approximately, that's why we use the symbol ≅)
b. 1.8 cm * 27'500,000 = 49'500,000 cm
Converting that amount to meters we have:
1 meter = 100 cm, thus:
49'500,000/100 = 495,000 meters but it's still too big to handle. Let's convert meters to kilometers, this way:
1 kilometer = 1,000 meters, thus:
495,000/1,000 = 495 km
The real distance from Sao Paulo to Belo Horizonte using the scale is ≅ 495 km (approximately, that's why we use the symbol ≅)
