Sheetal’s speed= 40 km/hr. Time taken by Sheetal = 5 hrs. Distance = Speed × Time = 40 × 5 = 200 km. ∴ Distance covered by Hemlata = 200 km. Time taken by Hemalata = 4 hrs. ∴ Hemlata’s Speed = (Distance )/Time = (200 )/4 = 50 km/hr. Sheetal’s increased speed= 50 km/hr. ∴ Time taken by Sheetal = (200 )/50 = 4 hrs. Hemlata’s increased speed = 60 km/hr. ∴ Time taken by Hemlata = (200 )/60 = 3(1/3) = 3hrs 20 minutes. ∴ Required difference = 4 hrs – 3hrs 20 minutes = 40 minutes.
