at a speed of 5 km/h. Then she increases her speed by 60% and takes 2 hours to reach village 'F'. What is the average speed of Sita from village 'D' to village 'F'?Solution
ATQ,
Distance between village 'D' and village 'E' = 5 × 6 = 30 km
Distance between village 'E' and village 'F' = 5 × 1.6 × 2 = 16 km
Total distance travelled by Sita = 30 + 16 = 46 km
Total time taken by Sita = 6 + 2 = 8 hours
