Answer 1

Очень просто!

1) 27 + 3 = 30 км в час

2)180 : 30 = 6 часов он потратит

Answer 2

#### Calculation of Time Taken by the Boat To calculate the time taken by the boat to travel from one pier to another and back, we need to consider the boat's speed and the speed of the current. Given: - Distance between the piers: 180 km - Boat's speed: 27 km/h - Speed of the current: 3 km/h To calculate the time taken by the boat, we can use the formula: **Time = Distance / (Boat's Speed + Speed of the Current)** Let's plug in the values and calculate the time taken by the boat: **Time = 180 km / (27 km/h + 3 km/h)** **Time = 180 km / 30 km/h** **Time = 6 hours** Therefore, the boat will take 6 hours to travel from one pier to another and back.
