A car travels along a path A-B-C-D (along segments AB, BC and CD). Points A, B, C, D are equidistant from each other, what was the speed of the car while travelling in the segment CD?
I. The total distance covered by the car is 288 km and the speed of the car in segment BC is 72 km/h.
II. The average speed of the car during the entire Journey is 72 km/h. The speed of the car to cover segments AB, BC and CD Is in the ratio of 15 : 12 : 10 respectively.1
The data in both the statements I and II together are necessary to answer the question.
2
The data either in statement I alone or in statement II alone are sufficient to answer the question.
3
The data in both the statements I and II together are not sufficient to answer the question.
4
The data in statement II alone are sufficient to answer the question, while the data in statement I alone are not sufficient to answer the question
5
The data in statement I alone are sufficient to answer the question, while the data in statement II alone are not sufficient to answer the question.
