Correct Answer: 72 km/h


Solution : Let the speed of the car be $x$ km/h.
According to the question,
Relative speed $= (x - 42)$ km/h
Distance $= 30 + 60 = 90$ km
Now the speed of the car will be
$⇒ x - 42 = \frac{90}{3}$
$⇒ x - 42 = 30$
$⇒ x = 30 + 42 = 72$ km/h
Hence, the correct answer is 72 km/h.
