Calculation of the Distance Traveled by the Bus

To calculate the distance traveled by the bus, we need to find the total distance covered during the two different time intervals.

The bus traveled for 2 hours at a speed of 45 km/h and then for 3 hours at a speed of 60 km/h. We can calculate the distance traveled during each interval using the formula:

Distance = Speed × Time

For the first interval of 2 hours at a speed of 45 km/h: Distance1 = 45 km/h × 2 hours

For the second interval of 3 hours at a speed of 60 km/h: Distance2 = 60 km/h × 3 hours

To find the total distance traveled by the bus, we add the distances covered during each interval:

Total Distance = Distance1 + Distance2

Let's calculate the distances and find the total distance traveled by the bus.

Calculation:

Distance1 = 45 km/h × 2 hours = 90 km Distance2 = 60 km/h × 3 hours = 180 km Total Distance = Distance1 + Distance2 = 90 km + 180 km = 270 km

Therefore, the bus traveled a total distance of 270 km during these 5 hours.

Please note that the calculations are based on the given information and assume a constant speed throughout each interval.
