C Correct answer
Explanation

Distance = Speed * Time. D1 = 50 * (20/60) = 16.67 km. D2 = 60 * (20/60) = 20 km. Total = 36.67 km.

AI explanation

We calculate the distance for each leg of the journey using the formula distance equals speed multiplied by time. For the first part, the car travels 50 km/hr multiplied by 20/60 hours, which gives 16.67 km. For the second part, the car travels 60 km/hr multiplied by 20/60 hours, which gives 20 km. Adding these distances, 16.67 plus 20, gives a total distance of 36.67 km. The total distance travelled by the car is 36.67 km.
