Question

Поїзд їхав перші 3 год зі швидкістю 80 км/год а в наступні 2 год він зменьшив швидкість 10 км/год яку відстань пройшов поїзд за весь цей час

Answer 1

80*3=240 (КМ)- Проїхав поїзд за 3 год
80-10=70 (км\год)- їхав поїзд
70*20=1400 (км) - проїхав за 2 год
1400+240=1640 км

Answer 2

Calculation of the Distance Traveled by the Train

To calculate the distance traveled by the train, we need to determine the distance covered during the first 3 hours and the distance covered during the next 2 hours.

1. Distance covered during the first 3 hours: - The train traveled at a speed of 80 km/h for 3 hours. - To calculate the distance, we can use the formula: distance = speed × time. - Therefore, the distance covered during the first 3 hours is: 80 km/h × 3 hours = 240 km.

2. Distance covered during the next 2 hours: - The train reduced its speed by 10 km/h, so the new speed is 80 km/h - 10 km/h = 70 km/h. - The train traveled at this reduced speed for 2 hours. - Using the same formula as before, the distance covered during the next 2 hours is: 70 km/h × 2 hours = 140 km.

3. Total distance traveled by the train: - To find the total distance, we add the distance covered during the first 3 hours to the distance covered during the next 2 hours. - Therefore, the total distance traveled by the train is: 240 km + 140 km = 380 km.

So, the train traveled a total distance of 380 km during this time.
