Question 4 Explanation:

Speed of the first car = 50 km/h

Speed of the second car = 60 km/h

Let no. of hours = x say

⇒ From the question we can write

(60)x – (50)x = 20

10x = 20

Speed of the second car = 60 km/h

Let no. of hours = x say

⇒ From the question we can write

(60)x – (50)x = 20

10x = 20

**∴ x = 2 hrs**Correct Answer: A
