Question

Маршрут в 544 км туристы преодолели в течение 5 часов на поезде,2 часов на автобусе и 4 часов пешком.Найдит скорость поезда ,если пешком они шли со скоростью 5,5 км/ч,что в 11 раз меньше, чем скорость автобуса.

Answer 1

1) 4ч х 5,5 км/ч =22км - прошли пешком

2) 2ч х (5,5 км/ч х 11)=121 км - проехали на автобусе

3) 544 - (22+121)= 401 км проехали в поезде

4)401км : 5 ч=80,2 км/ч- скорость поезда

Answer 2

Calculating the Train's Speed

To find the speed of the train, we can use the formula: speed = distance / time

The total distance covered by the tourists is 544 km. The time taken for each mode of transport is as follows: - Train: 5 hours - Bus: 2 hours - Walking: 4 hours

First, let's calculate the total time taken for the journey: Total time = 5 hours (train) + 2 hours (bus) + 4 hours (walking) = 11 hours

Now, we can calculate the speed of the train using the formula: Speed of train = Distance / Time

Speed of train = 544 km / 5 hours Speed of train = 108.8 km/h

So, the speed of the train is 108.8 km/h.

Walking Speed and Bus Speed

The tourists walked at a speed of 5.5 km/h, which is 11 times slower than the speed of the bus.

Conclusion

The speed of the train is 108.8 km/h. The tourists walked at a speed of 5.5 km/h, which is 11 times slower than the speed of the bus.
