On the scale of 1:2000000, the distance between the two cities is 6cm. What is the actual distance?
6 △ 12000000, = 6 × 2000000, = 12000000 (CM), 12000000 cm = 120km; a: the actual distance between the two cities is 120km
On a map with a scale of 1:2000000, the length of a and B is 5.5cm. If you draw it on a map with a scale of 1:50000, what is the distance on the map of this highway
It can be seen that the actual distance between the two places is 5.5 * 2000000
If redrawn, the distance on the map is 5.5 * 2000000 / 5000 = 220cm
On a map with a scale of 1:2000000, the distance between a and B is 5cm
1/2000000=5/x
x=10000000
1/2500000=x/10000000
x=4
On the map with a scale of 1:2000000, the distance between a and B is 3.6cm. If the car starts from a place at 8 a.m. at the speed of 30km / h, what time does it take to arrive at B place?
3.6 △ 1 / 2000000 = 7500000cm
7500000cm=75km
75 △ 30 = 2.5 hours
2.5+8=9.5=9：30
On a map with a scale of 1:2000000, the distance between a and B is 3.6cm,
If the car leaves at 8 a.m. at the speed of 36 km / h, what time can it reach B?
3.6 × 200000 = 7200000 cm = 72km
When 72 △ 36 = 2
A: then we can get to B at 10 o'clock
