Question

Расстояние между 2 городами 261,15 км.Поезд за 1,8 часапроехал со скоростью 79,15 км/ч а остальное расстояние проехал за 1,5 часа . С какой скорости проехал ?

Answer 1

1) 79,15 * 1,8 = 142,47 км первая часть пути
2) 261,15 - 142,47 = 118,68 км вторая часть пути
3) 118,68 : 1,5 = 79,12 км/ч  скорость на втором участке пути

Answer 2

Calculating Speed of the Train

To calculate the speed at which the train traveled the remaining distance, we can use the formula:

Speed = Distance / Time

First, let's calculate the distance and time for each part of the journey.

1. Distance and Time for the First Part of the Journey: - Distance: 79.15 km/h * 1.8 h = 142.47 km - Time: 1.8 hours - Speed: 79.15 km/h

2. Distance and Time for the Second Part of the Journey: - Distance: Total distance - Distance traveled in the first part = 261.15 km - 142.47 km = 118.68 km - Time: 1.5 hours

Now, we can calculate the speed at which the train traveled the remaining distance.

Calculating the Speed for the Second Part of the Journey

Using the formula Speed = Distance / Time, we can calculate the speed for the second part of the journey:

Speed = 118.68 km / 1.5 h

Speed = 79.12 km/h

So, the train traveled the remaining distance at a speed of 79.12 km/h.
