On the map with a scale of 1:2000000, the distance between Jinan and Yantai is measured to be 3.6cm. If the speed of the car is 30km / h, it will leave at 9am When is the time to start from the South and finish the journey to Yantai?

3.6/1:2000000=7200000（cm）
7200000/100/1000=72（km）
72/30=2.4（h）=2h24min
9:00+2h24min=11:24

On the map with a scale of 1:2000000, the distance between a and B is 3.6cm. If the car starts from a at 9am at the speed of 30km / h, when will it arrive at B?

Actual distance = 3.6 * 2000000 = 7200000 cm = 72km
72 △ 30 = 2.4 hours = 2 hours 24 minutes
It's 11:24 after the journey to B

2. It is stipulated that the speed of a vehicle should not exceed 70 km / h on a certain highway. When a traffic accident occurs, the traffic police usually estimate the speed of the vehicle according to the sliding distance of the wheel after braking. The empirical formula used is v = 16 √ DF, where V is the vehicle speed (unit: km / h), D is the sliding distance of the wheel after braking (unit: m), and F is the friction factor, D = 20m, f = 1.2m, did the speed of the car exceed the specified speed?
