Final answer:
The school bus traveled a distance of 37.5 km.
Step-by-step explanation:
To find the distance traveled, we can use the formula:
Distance = Speed x Time
Given that the school bus travels at a speed of 50 km/hr for 45 minutes, we first need to convert the time to hours. 45 minutes is equivalent to 0.75 hours (since there are 60 minutes in an hour and 45/60 = 0.75).
Plugging in the values into the formula:
Distance = 50 km/hr x 0.75 hr = 37.5 km
Therefore, the school bus traveled a distance of 37.5 km.
