Two cars A and B travel from one city to another city, at speeds of 60 km/hr and 108 km/hr, respectively. If car B takes 2 hours lesser time than car A for the journey, then what is the distance (in km) between the two cities?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 270
Let A take 't' hrs
then, B takes (t - 2) hrs
ATQ,
60t = 108(t - 2)
216 = 48t
t = 9/2 hrs
Distance between two cities = 60 × 9/2 = 270 km
