A) 5 km/hr
B) 15 km/hr
C) 25 km/hr
D) 35 km/hr
Correct Answer: B
Solution :
Here, the two speeds are \[40\,\,km/hr\] and\[25\,\,km/hr\]. \[u=40\,\,km/hr\] and \[v=25\,\,km/hr\] Relative speed\[=(u-v)km/hr\]. \[=(45-25)km/hr\]. \[=15\,\,km/hr\]. Hence, the relative speed of the two cars is\[15\,\,km/hr\].You need to login to perform this action.
