Answer 2

Calculation of the Bus Speed

To calculate the speed of the bus, we need to know the distance traveled and the time taken. In this case, we know that the bus traveled 30 km in 3/4 of an hour.

To find the speed, we can use the formula:

Speed = Distance / Time

Given that the distance is 30 km and the time is 3/4 of an hour, we can substitute these values into the formula to find the speed.

Speed = 30 km / (3/4) hour

To simplify the calculation, we can convert 3/4 of an hour to minutes. Since there are 60 minutes in an hour, 3/4 of an hour is equal to 45 minutes.

Speed = 30 km / 45 minutes

Now, we can calculate the speed:

Speed = 30 km / 45 minutes = 0.67 km/minute

Therefore, the speed of the bus is 0.67 km/minute.

Please note that the above calculation assumes a constant speed throughout the journey. If the speed varied during the 3/4 hour, the average speed would be calculated differently. However, since the question does not provide any additional information, we assume a constant speed for simplicity.
