Speed of Dee - Speed of Bee = 34 kmph
Distance =Speed of Dee × 8/60(hours) = Speed of Bee × 25/60(hours)
= Speed of Dee × 8/60(hours) = (Speed of Dee - 34) × 25/60(hours)
= Speed of Dee = (Speed of Dee - 34) × 25/8
= Speed of Dee = Speed of Dee × 25/8 - 34 × 25/8
= 34×25/8 = Speed of Dee × 25/8 - Speed of Dee
= 34×25/8 = Speed of Dee × 17/8
Speed of Dee = 34×25×8/(8×17) = 50 Kmph
Speed of Bee = 50 - 34 = 16 Kmph
Speed of Lee = 16/4 = 4 Kmph.
