"Encounter Problems" Use Equations to Solve Problems PPT Courseware

The distance from Naughty’s house to Xiaoxiao’s house is 840m, and they both set off from home at the same time.

The distance traveled by Naughty + the distance walked by Xiaoxiao = 840 meters

Naughty speed × time + Xiaoxiao speed × time = 840 meters

1. Uncle Zhang wanted to deliver a piece of material to Aunt Wang, and they agreed that they would drive out at the same time. The park is 50km away from the overpass.

⑴Where do you think the two met? Mark it on the picture and share your thoughts with a partner.

⑵When will we meet after departure? How far is the meeting point from the park? Solve problems using equations.

2. Two engineering teams, A and B, are paving a 1400m long road. They are working from both ends at the same time. Team A is paving 80m every day and Team B is paving 60m every day. How many days will it take to complete the road?

There is a 5,700-word document. Due to time constraints, two typists A and B were arranged to start typing at the same time. How long does it take to record this document?

The railway from Beijing to Hohhot is 660km long. One train leaves from Hohhot and travels 60km per hour; the other train leaves from Beijing and travels 72km per hour. Two trains leave at the same time. How long will it take for them to meet?
