A toy car follows the path from P to T via points Q,
R and S over an time interval of 60 s as shown in the
given figure. The distance travelled while changing
the direction can be neglected. Assume the speed to
be constant throughout the motion.
What is car’s average speed between P and T ?
A1 m/s
B4 m/s
C2 m/s
D8 m/s
