From a to B, the car can complete the whole journey in 6 hours, and the bus can complete 1 / 12 of the whole journey in 2 / 3 hours Don't use equations. Write them clearly

From a to B, the car can complete the whole journey in 6 hours, and the bus can complete 1 / 12 of the whole journey in 2 / 3 hours Don't use equations. Write them clearly

Time to meet?
Bus speed: 1 / 12 △ 2 / 3 = 1 / 8
Meeting time: 1 ÷ (1 / 6 + 1 / 8) = 24 / 7 (hours)

The distance from city a to city B is 800 kilometers. A car takes 35% of the whole journey in the first 6 hours. At this speed, how many hours does it take to complete the whole journey?

6 △ 35 = 10 (hours) a: it takes 10 hours to complete the whole journey

A car can travel 480 kilometers in 8 hours. In fact, it can travel 5 / 6 of the whole journey in 5 hours. In this way, it can travel several hours in advance
A car can travel 480 kilometers in 8 hours. In fact, it can travel 5 / 6 of the whole journey in 5 hours. How many hours ahead of time can it travel?

The actual time is 1 × 5 (5 / 6) = 6 hours;
Lead time = 8-6 = 2 hours;

Ask a 174 km long highway. It takes a car 1.5 hours to travel 4 km. At this speed, how many hours will it take to complete the whole journey
Here's what I do: (170-4) / (4 / 1.5)
I want a complete solution

What grade? 175 divided by 4 multiplied by 1.5 and subtracted 1.5
