Answer 1

1) 108:54=2(ч)
2) 162:54=3(ч)
3) 2ч+3ч+20мин=5ч20мин

Answer 2

1) 108:54=2(ч) - он был в пути ДО остановки.
2) 162:54=3(ч) - он был в пути ПОСЛЕ остановки.
3) 2ч+3ч+20мин=5ч20мин - он был в пути.

Answer 3

Calculating the Total Travel Time

To calculate the total time the bus was in transit, we can break down the journey into two parts: the time taken to travel the first 108 km and the time taken to travel the subsequent 162 km.

First 108 km: The bus traveled the first 108 km at a speed of 54 km/h.

Time taken to travel the first 108 km: To calculate the time taken, we can use the formula: time = distance / speed.

So, time = 108 km / 54 km/h = 2 hours.

Stoppage: The bus made a stop for 20 minutes after traveling the first 108 km.

Next 162 km: After the stoppage, the bus traveled the next 162 km at the same speed of 54 km/h.

Time taken to travel the next 162 km: Similar to the first part, the time taken to travel the next 162 km can be calculated using the formula: time = distance / speed.

So, time = 162 km / 54 km/h = 3 hours.

Total Time in Transit

To find the total time the bus was in transit, we add the time taken for the first 108 km, the stoppage time, and the time taken for the next 162 km.

Total time in transit: Total time = Time for first 108 km + Stoppage time + Time for next 162 km Total time = 2 hours + 20 minutes + 3 hours Total time = 5 hours + 20 minutes

Therefore, the bus was in transit for 5 hours and 20 minutes.

Answer 4

Calculation of the Total Time the Bus Was in Transit

To calculate the total time the bus was in transit, we need to consider the time it took for the bus to travel 108 km, the 20-minute stop, and the time it took for the bus to travel an additional 162 km.

Let's break down the calculation step by step:

1. Time taken to travel 108 km: - The bus was traveling at a speed of 54 km/h. - To calculate the time taken, we divide the distance by the speed: 108 km / 54 km/h = 2 hours.

2. Time spent during the 20-minute stop: - The bus made a stop for 20 minutes. - We don't need to convert this time to hours since we'll be adding it to the total time in hours later.

3. Time taken to travel an additional 162 km: - The bus traveled 162 km at the same speed of 54 km/h. - To calculate the time taken, we divide the distance by the speed: 162 km / 54 km/h = 3 hours.

4. Total time the bus was in transit: - We add the time taken for each segment: 2 hours + 0.33 hours (20 minutes converted to hours) + 3 hours = 5.33 hours.

Therefore, the bus was in transit for approximately 5 hours and 20 minutes.
