Question

СМОЖЕТ ЛИ ПОЕЗД ПРОЙТИ 300КМ ЗА 7 ЧАСОВ, ЕСЛИ ОН БУДЕТ ДВИГАТЬСЯ СО СКОРОСТЬЮ 60КМ/Ч И ПРИ ЭТОМ 2 ЧАСА ТРАТИТЬ НА ОСТАНОВКИ?

Answer 1

1) 7-2=5(ч) без остановок

2)300/5=60(км/ч) скорость

Answer 2

Can a train travel 300 km in 7 hours if it moves at a speed of 60 km/h and spends 2 hours on stops?

To determine if a train can travel 300 km in 7 hours while moving at a speed of 60 km/h and spending 2 hours on stops, we need to calculate the total time it would take for the train to cover the distance.

Let's break down the time calculation:

1. Time spent on stops: 2 hours. 2. Time spent on actual travel: To find this, we can divide the distance by the speed of the train. The formula is: time = distance / speed. In this case, the distance is 300 km and the speed is 60 km/h. So, the time spent on actual travel is 300 km / 60 km/h = 5 hours.

Now, we can calculate the total time:

Total time = Time spent on stops + Time spent on actual travel = 2 hours + 5 hours = 7 hours.

Based on the calculations, the total time required for the train to travel 300 km, including the time spent on stops, is 7 hours. Therefore, the train would be able to complete the journey within the given time frame.

Please note that these calculations assume a constant speed throughout the journey and do not account for other factors such as acceleration, deceleration, or delays.
