How many kilometers did they travel from home to the railway station? 2. Li Ping took a taxi for 18 kilometers. How much is the fare?


Distance = (17.6-8) △ 1.2 + 2.5 = 10.5km
2. Payable = (18-2.5) × 1.2 + 8 = 26.6 yuan



The starting price of a taxi is 10 yuan (i.e. 10 yuan for a distance of more than 5 km). After reaching 5 km, 1.2 yuan will be added for each additional kilometer (the part less than 1 km will be counted as 1 km). Now someone takes a taxi from place a to place B and pays 17.2 yuan. How much is the distance from place a to place B?


(17.2-10) △ 1.2 = 6 km
5 + 6 = 11km
Because less than 1 km is also calculated as 1 km
Therefore, the distance from a to B is about 10-11, that is, 10 km < distance ≤ 11 km



The starting price of a taxi in a village is 7 yuan (driving no more than 5km). After that, for every 1km increase, the price will be increased by 1.5 yuan. Now someone takes a taxi for X km
What is the cost of (x > 5)?


Cost: 7 + 1.5 (X-5) = 1.5x-0.5 (x > 5)
