A) 42m/s
B) 15m/s
C) 9m/s
D) 54m/s
Correct Answer: B
Solution :
[b] Total time taken is 42 hours. Total distance is 2268 km. So, \[Speed=\frac{\text{Distance}}{\text{Time}}\] If it is km/ hour then we have to multiply this with \[\frac{5}{18}\] to convert in min/sec. \[=\frac{2268}{42}\times \frac{5}{18}=15\,\min /\sec \]You need to login to perform this action.
