Constant motion

The car has undergone constant motion 120 km in 1 hour 30 minutes. Determine its average speed. Determine how long car drove in the first 20 minutes and 50 minutes from the start of the move.

Correct result:

v =  80 km/h
s1 =  26.6667 km
s2 =  66.6667 km

Solution:

s=120 km t=1+30/60=32=1.5 h  v=s/t=120/1.5=80 km/h
t1=20 min h=20/60  h=0.33333 h s1=v t1=80 0.3333=803=26.6667 km
t2=50 min h=50/60  h=0.83333 h s2=v t2=80 0.8333=2003=66.6667 km
