Question

Скорость автобуса на трассе 90км/ч расстояние мужду конечными пунктами 280км успеет ли автобус пройти маршрут за 3 ч? сколько проедет автобус за 3 ч

Answer 1

Нет. За 3 часа он пройдет только 270км                                                           Так как 90*3=270(км). А 280>270.

Answer 2

Не успеет, за 3 часа проедет: 3*90=270км

Answer 3

Calculating the Bus Speed and Distance

To determine if the bus can complete the route in 3 hours, we need to calculate the bus's speed and the distance it can cover in that time.

The speed of the bus on the highway is 90 km/h. The distance between the endpoints is 280 km.

Calculating the Time Required

To calculate if the bus can complete the route in 3 hours, we can use the formula: \[ \text{Time} = \frac{\text{Distance}}{\text{Speed}} \]

Substituting the given values: \[ \text{Time} = \frac{280 \text{ km}}{90 \text{ km/h}} \] \[ \text{Time} \approx 3.11 \text{ hours} \]

Conclusion

The bus will take approximately 3.11 hours to cover the 280 km distance at a speed of 90 km/h. Therefore, it will not be able to complete the route in 3 hours.

Additional Information

If the bus travels for 3 hours at a speed of 90 km/h, it will cover a distance of: \[ \text{Distance} = \text{Speed} \times \text{Time} \] \[ \text{Distance} = 90 \text{ km/h} \times 3 \text{ hours} = 270 \text{ km} \]

Therefore, the bus will cover approximately 270 km in 3 hours.
