Question
Asha travels 40.5 km in 1 hour and 30 minutes. How far will she travel in 4 hours if her speed increases by 3 km/h?
Solution
ATQ,
30 minutes = (30/60) = 0.5 hours
So, usual speed of Asha = (40.5 / 1.5) = 27 km/h
Increased speed of Asha = 27 + 3 = 30 km/h
Therefore, distance covered by her in 4 hours = 30 × 4 = 120 km
