A) zero
B) 60 km/h
C) 6 km/h
D) 180 km/h
Correct Answer: C
Solution :
[c] As we know that, the total distance covered, s = final reading of odometer - initial reading of odometer |
= (4460 - 4200) km = 260 km |
Total Displacement = 0 km |
Total time taken, t=4 h 20 min = 4.33h |
Total displacement |
\[\therefore \operatorname{Average} velocity=\frac{Total displacement(d)}{Total time taken(t)}\] |
\[=\frac{0}{4.33}=0\] |
