Mathematics Diary - Choose public transportation for green travel

Yin Quanlai, a tutor from Class 3.4 of Chuangxin Street Primary School, Lin Yuan

Winter vacation is a good time for us to have fun. After visiting the Henan Provincial Geological Museum, I went to my favorite place - the Science and Technology Museum to explore the mysteries of science. I was really happy! My father said we should go by car, my sister said we should take a taxi, and my mother and I said we should take the bus. Aren’t we going to have a low-carbon and environmentally friendly Spring Festival? Then let’s figure out how to travel in the most environmentally friendly way, and then choose the mode of transportation we take.

Dad said that it is about 5 kilometers from our home on Dongjie Street to the Science and Technology Museum. We walked along the bus route of Dongjie Street-Erqi Square-Zhongyuan Road, choosing taxis and buses respectively. , private cars and other different means of transportation, compare the time and cost respectively to see how much it costs to walk to the Science and Technology Museum. This is not a problem for me, it can be calculated by multiplication.

By taxi: It takes 20 minutes to get there if there is no traffic jam, and the cost is 10 yuan.

Taking the bus: 1 yuan coin, 8 jiao credit card, 2 liters of diesel/km, about 6 yuan/liter. It can be reached in 30 minutes without traffic jams, and the cost is about 1 yuan/person. times; the total cost for the four of us was 4 yuan, and the bus can seat dozens of people.

Taking a private car: If there is no traffic jam, it takes 20 minutes to arrive. It will cost 0.5 liters of gasoline (97#), 7.63 yuan/liter, and a parking fee of 4 yuan. The total cost is: 0.5×7.63＝3.8 (yuan) 3.8 4 = 7.8 (yuan)

From the above calculation, we can see that taking a taxi or a private car can reach your destination faster than taking a bus, but the cost is higher and it is wasteful It uses more energy; although taking a bus takes longer, the cost is very small. Moreover, one bus can carry many people, saving a lot of energy! Therefore, taking the bus is the most environmentally friendly way to travel.

Our family happily set off and arrived at the bus station. A bus came from a distance with eye-catching slogans written on the body: low-carbon travel, green bus. We must insist on green travel and contribute our part to protect Mother Earth and our living environment.
