Answer 2

Calculation of the Route Duration

To calculate the duration of the route, we need to add the time it takes to travel from Rokytne to Yabluneve (t) and the time it takes to travel from Yabluneve to Verbnе (t').

Let's denote the distance from Rokytne to Yabluneve as d1 and the distance from Yabluneve to Verbnе as d2. We are given that d2 = 165 km.

The formula to calculate the duration of a trip is:

Duration = Distance / Speed

1. Calculation of the duration from Rokytne to Yabluneve:

Duration1 = d1 / v

2. Calculation of the duration from Yabluneve to Verbnе:

Duration2 = d2 / v

3. Calculation of the total duration of the route:

Total Duration = Duration1 + Duration2

Let's substitute the given values into the formula to calculate the duration of the route.

Calculation for t = 1 hour and v = km/h

1. Calculation of the duration from Rokytne to Yabluneve:

Duration1 = d1 / v = t

Since we are given that t = 1 hour, we can conclude that the duration from Rokytne to Yabluneve is 1 hour.

2. Calculation of the duration from Yabluneve to Verbnе:

Duration2 = d2 / v

Since we are given that d2 = 165 km and v = km/h, we can calculate the duration from Yabluneve to Verbnе using the formula:

Duration2 = 165 km / v

However, we are not given the value of v, so we cannot calculate the exact duration from Yabluneve to Verbnе.

3. Calculation of the total duration of the route:

Total Duration = Duration1 + Duration2

Since we know that Duration1 = 1 hour and we don't have the value of Duration2, we cannot calculate the total duration of the route.

Calculation for t = 2 hours and v = 55 km/h

1. Calculation of the duration from Rokytne to Yabluneve:

Duration1 = d1 / v

Since we are given that t = 2 hours and v = 55 km/h, we can calculate the duration from Rokytne to Yabluneve using the formula:

Duration1 = 2 hours

2. Calculation of the duration from Yabluneve to Verbnе:

Duration2 = d2 / v

Since we are given that d2 = 165 km and v = 55 km/h, we can calculate the duration from Yabluneve to Verbnе using the formula:

Duration2 = 165 km / 55 km/h = 3 hours

3. Calculation of the total duration of the route:

Total Duration = Duration1 + Duration2

Total Duration = 2 hours + 3 hours = 5 hours

Therefore, if the time taken to travel from Rokytne to Yabluneve is 2 hours and the speed is 55 km/h, the total duration of the route from Rokytne to Verbnе is 5 hours.

Please note that the exact duration from Yabluneve to Verbnе depends on the speed (v), which is not provided in the question.
