1.  Robert is travelling on his cycle and has calculated to reach point A at 2 P.M. if he travels at 10 kmph, he will reach there at 12 noon if he travels at 15 kmph. At what speed must he travel to reach A at 1 P.M.? 

Answer: Option C Explanation: Let the distance travelled by x km.
3x  2x = 60 x = 60 km.
So, Robert started 6 hours before 2 P.M. i.e., at 8 A.M.
