Question

a bus trip covers 191 km and takes 4 hours and 15 minutes, what is the average speed of the bus in kilometers per hour

Answer 1

Answer: 44,94 km/h

Step-by-step explanation: 15 minutes is a quarter of hour. So we can write 4h + (1/4)h = 17/4 = 4,25 h.

As the average speed is calculated dividing distance by time, the result is 191/ 4,25 = 44,94 km/h.
