Calculation of Departure Time from Moscow to Klin

To calculate the departure time from Moscow to Klin, we need to consider the speed of the motorcyclist, the distance between the two cities, and the duration of the two stops.

Given information: - Speed of the motorcyclist: 45 km/h - Distance from Moscow to Klin: 90 km - Duration of the first stop: 25 minutes - Duration of the second stop: 35 minutes - Arrival time in Klin: 13:20

To calculate the departure time, we need to determine the total travel time and subtract it from the arrival time.

1. Calculate the travel time: - The motorcyclist traveled a distance of 90 km at a speed of 45 km/h. - Time = Distance / Speed = 90 km / 45 km/h = 2 hours

2. Calculate the total duration of the stops: - First stop: 25 minutes - Second stop: 35 minutes - Total stop duration = 25 minutes + 35 minutes = 60 minutes = 1 hour

3. Calculate the total travel time including the stops: - Total travel time = Travel time + Total stop duration = 2 hours + 1 hour = 3 hours

4. Subtract the total travel time from the arrival time to find the departure time: - Departure time = Arrival time - Total travel time = 13:20 - 3 hours = 10:20

Therefore, the motorcyclist departed from Moscow to Klin at 10:20.

Please note that the above calculation assumes a constant speed throughout the journey and does not account for other factors such as traffic or road conditions.
