Question

Автобус прошел d км за 3 ч. какое расстояние он пройдет за 7 ч, двигаясь с той же скоростью?

Answer 1

Он проедет 2,5d км. Скорость не меняется, а время увеличилось. Значит растояние увеличилось пропорционально времени. Время увеличилось в 7:3=2,5 раза. И так растояние увеличитса в 2,5раза и станет 2,5d

Answer 2

Problem Analysis

We are given that a bus traveled a distance of d km in 3 hours. We need to find the distance it will travel in 7 hours, assuming it maintains the same speed.

Solution

To find the distance the bus will travel in 7 hours, we can use the formula:

Distance = Speed × Time

Since the speed of the bus remains the same, we can use the speed from the given information. Let's assume the speed of the bus is v km/h.

Using the formula, we can write the equation:

d km = v km/h × 3 h

We need to find the distance the bus will travel in 7 hours, so we can write another equation:

Distance = v km/h × 7 h

To solve for the distance, we can substitute the value of v from the first equation into the second equation:

Distance = (d km / 3 h) × 7 h

Simplifying the equation, we get:

Distance = (7/3) × d km

Therefore, the bus will travel (7/3) × d km in 7 hours, assuming it maintains the same speed.

Answer

The bus will travel (7/3) × d km in 7 hours, assuming it maintains the same speed.
