Question

Теплоход шел по озеру 2 часа со скоростью 42 километров час затем 3 часа вверх по реке со скоростью 40 километров час какой путь прошел теплоход

Answer 1

42*2=84
40*3=120
120+84=204 веь путь

Answer 2

2х42=84км прошел по озеру
3х40=120км по реке
120+84=204км путь теплохода

Answer 3

Calculating the Distance Traveled by the Boat

To calculate the distance traveled by the boat, we can use the formula: distance = speed × time.

Given: - Speed on the lake = 42 kilometers per hour - Time on the lake = 2 hours - Speed upstream on the river = 40 kilometers per hour - Time upstream on the river = 3 hours

Using the formula, we can calculate the distance traveled on the lake and upstream on the river separately, and then add them together to find the total distance traveled.

Distance Traveled on the Lake

The distance traveled on the lake can be calculated using the formula: distance = speed × time.

Distance on the lake = 42 km/h × 2 h = 84 km.

Distance Traveled Upstream on the River

The distance traveled upstream on the river can also be calculated using the formula: distance = speed × time.

Distance upstream on the river = 40 km/h × 3 h = 120 km.

Total Distance Traveled

To find the total distance traveled, we add the distance on the lake to the distance upstream on the river.

Total distance traveled = 84 km + 120 km = 204 km.

Therefore, the boat traveled a total distance of 204 kilometers.
