Question

Автобус ехал со скоростью 54км/ч.Через 3 часа он проехал 9-ять 14-атых своего пути.Чему равен весь путь автобуса? С какой скоростью ему надо ехать, чтобы пройти оставшийся путь за 2 часа?

Answer 1

54*3=162(км)- проехал автобус за 3 часа.
162:9*14=252(км) - весь путь
252-162=90 (км) - осталось проехать автобусу.
90:2=45(км/ч) - скорость автобуса на оставшемся пути.
Ответ: 252 км весь путь автобуса; 45 км/ч скорость автобуса на оставшемся пути.

Answer 2

Calculation of the Total Distance Traveled by the Bus

To calculate the total distance traveled by the bus, we need to use the formula:

Distance = Speed × Time

Given that the bus was traveling at a speed of 54 km/h and it traveled for 3 hours, we can calculate the distance traveled during this time:

Distance = 54 km/h × 3 hours

Using this formula, we find that the bus traveled a distance of 162 kilometers in the first 3 hours.

Calculation of the Remaining Distance and Required Speed

Next, we need to calculate the remaining distance that the bus needs to cover and the speed at which it should travel to cover that distance in 2 hours.

According to the information provided, after 3 hours, the bus had traveled 9-14ths of its total distance. To find the remaining distance, we need to subtract the distance traveled from the total distance:

Remaining Distance = Total Distance - Distance Traveled

Since we don't know the total distance yet, we'll represent it as D:

Remaining Distance = D - 162 km

To find the required speed, we can use the formula:

Required Speed = Remaining Distance / Time

Given that the bus needs to cover the remaining distance in 2 hours, we can calculate the required speed:

Required Speed = (D - 162 km) / 2 hours

Now, we have two equations:

1. Remaining Distance = D - 162 km 2. Required Speed = (D - 162 km) / 2 hours

To solve these equations, we need more information or additional equations. Unfortunately, the given information is not sufficient to determine the exact values of the remaining distance and the required speed.

Please provide more information or equations to solve the problem accurately.
