Answer:
Relative speed between both the cars is (60-42) = 18 km/hr = 5 m/s
 
both the cars have length 5 m, hece to cross completely required distance to be travelled is 10 m.
 
hence time taken to overtake = 10/5 = 2 seconds.
 
distance travelled by the overtaking car = begin mathsize 12px style 60 space k m divided by h r space cross times open parentheses 5 over 18 close parentheses space fraction numerator m divided by s over denominator k m divided by h r end fraction space cross times space 2 space s equals space 33.33 space m end style
