On the map with the scale of 1:2000000, the distance between a and B is 3.6cm. If the car starts from a place at 8 am at the speed of 60km / h, what time is it to arrive at B place?
Actual distance = 3.6x20 = 72km
72 △ 60 = 1.2 hours, i.e. 1 hour 12 minutes
So starting at 8 a.m. from place a, then arriving at place B is 9:12
On a map with a scale of 1:2000000, the distance between a and B is 9cm. How many hours does it take for a car to arrive at a speed of 60km / h from place a to place B?
First, through the map scale, calculate the distance between a and B: 2000000 × 9 = 18000000cm
Next, convert 18000000cm into km, which is equal to 180km
Last 180 km △ 60 = 3 hours
