Answer 1

228:48=4,75 (ч)- время туда
228:36=8 (ч)

Answer 2

Calculation of Travel Time

To determine which trip took longer, we need to calculate the travel time for each leg of the journey.

The distance between points A and B is given as 228 km.

The car traveled from point A to point B at a speed of 48 km/h, and returned from point B to point A at a speed of 36 km/h.

To calculate the travel time, we can use the formula:

Travel Time = Distance / Speed

Let's calculate the travel time for each leg of the journey:

1. Travel time from A to B: - Distance: 228 km - Speed: 48 km/h - Travel Time = 228 km / 48 km/h = 4.75 hours

2. Travel time from B to A: - Distance: 228 km - Speed: 36 km/h - Travel Time = 228 km / 36 km/h = 6.33 hours

Comparison of Travel Times

Based on the calculations, we can see that the trip from point B to point A took longer. The travel time from A to B was 4.75 hours, while the travel time from B to A was 6.33 hours.

Therefore, the trip from B to A took longer by 1.58 hours.

Please note that these calculations assume a constant speed throughout the journey and do not account for factors such as traffic or breaks.
