Sam had a 100 m head start on Ricky but Ricky could negate that in 2 min, meaning Ricky was 50m/min faster than Sam. Since Sam walked at 140m/min, Ricky was walking at 190m/min. Tina had a 400m head start on Ricky but Ricky negated that distance in 4 min, hence Ricky was 100m/min faster than Tina. Since Ricky has been determined to walk at 190m/min, Tina must be walking at 90 m/min. Similarly, Tina had a 300m head start on Sam, but Sam was 140-90=50m/min faster. Hence Sam could negate that 300m head start Tina had on him in 300/50 = 6 min 6 minutes after 0930 was 0936.
