Answer:
B
Explanation:
The time taken to reach the destination is given as 3x hours. The distance to the destination is given as 40 * 3x = 120x km. The person has traveled a distance of 2/3 * 120x = 80x km in 1/3 * 3x = x hours. Therefore, to reach the destination, the person must travel the remaining distance of 40x km in 2x hours. To find the required speed, we can use the formula speed = distance / time. Plugging in the values given in the problem, we get speed = 40x km / 2x hours = 20 km/hr.
