Question
Vijay can cover a distance D with speed S in time T. He can cover the same distance with speed (S + 10) in time (T - 2). He can cover the same distance D with speed (S - 15) in time (T + 6). Based on this data, which of the following can be found?
(i) Time to cover 200 km with speed (S + 10)
(ii) Distance covered in (T + 6) time with speed (S + 10)
(iii) Speed by which a tunnel can be crossed in \frac{T}{2} hour
(iv) Ratio between time to cover distance D with speed S to time to cover distance (D - 5) with speed (S + 10)
