You ride your bike for 1.9 h at an average velocity of 10 km/h, then for 30 min at 11 km/h. What is your average velocity?

Average velocity

= total distance travelled / total time

Total distance = 1.9h*10 km/h + 0.5h*11km/h

Total time = 1.9h+0.5h

So average velocity = ?

11.25 km/h

Average velocity is the total displacement divided by the total time.

t1= 1.5 hour (time)

t2= 30 minutes (time)

v1= 10 km/h (velocity)

v2= 18 km/h (velocity)

d1= 10 km/h x 1.5 hour = 15 km

d2= 15 km/h x 0.5 minutes = 7.5 km *convert the minutes to hour to get the answer 7.5*

15 km + 7.5 km (add the distance) = 22.5

---------------

1.5 h + 0.5 = 2 (divided by time) = 2

so, the answer will be 11.25 km/h.
