Question

ТЕПЛОХОД ШЁЛ ПО ОЗЕРУ 2 ЧАСА СО СКОРОСТЬЮ 42 КМ/Ч ЗАТЕМ 3 ЧАСА ВВЕРХ ПО РЕКЕ СО СКОРОСТЬЮ 40 КМ/Ч КАКОЙ ПУТЬ ПРОШЁЛ ТЕПЛОХОД С ОТВЕТОМ?

Answer 1

42*2=84 км по озеру 40*3=120 км по реке 48+120=168 км прошел путь теплоход

Answer 2

2ч*42км/ч + 3ч*40км/ч = 204

Answer 3

Calculation of the Distance Traveled by the Boat

To calculate the distance traveled by the boat, we need to consider the two different segments of the journey: the time spent on the lake and the time spent traveling upstream on the river.

1. Time spent on the lake: The boat traveled on the lake for 2 hours at a speed of 42 km/h. To calculate the distance traveled on the lake, we can use the formula: distance = speed × time. Therefore, the distance traveled on the lake is 42 km/h × 2 hours = 84 km.

2. Time spent traveling upstream on the river: The boat then traveled upstream on the river for 3 hours at a speed of 40 km/h. To calculate the distance traveled upstream, we can again use the formula: distance = speed × time. Therefore, the distance traveled upstream is 40 km/h × 3 hours = 120 km.

3. Total distance traveled: To find the total distance traveled by the boat, we add the distance traveled on the lake to the distance traveled upstream on the river. Therefore, the total distance traveled by the boat is 84 km + 120 km = 204 km.

So, the boat traveled a total distance of 204 km.
