A) 46km/hr
B) 50km/hr
C) 49 km/hr
D) 60 km/hr
Correct Answer: B
Solution :
Total distance travelled = 300 + 400 = 700 km Total time taken = 5.5 + 8.5 = 14hrs. Total distance travelled \[\therefore \] Average speed \[=\frac{\text{Total}\,\text{distance}\,\text{travelled}}{\text{Total}\,\text{Time}\,\text{taken}}\] \[=\frac{700}{14}=50\,km/hr\].You need to login to perform this action.
