a bicycle travel 12km in 40 min, what is its average speed

12km/40min = 0.3 km/min

18 To find the average speed of the bicycle, we need to divide the total distance traveled by the time taken. In this case, the bicycle traveled 12 km in 40 minutes.

Average speed = Total distance / Time taken

For the given values:
Total distance = 12 km
Time taken = 40 minutes

Now, let's convert the time from minutes to hours, as speed is usually measured in kilometers per hour.

1 hour = 60 minutes

40 minutes = 40 / 60 = 0.67 hours (approximately)

Average speed = 12 km / 0.67 hours

Using these values, we can calculate the average speed of the bicycle.
