When Sourav increases his speed from 20 Km/hr to 25 Km/hr, he takes one hour less than the usual time to cover a certain distance. What is the distance usually covered by him?

1. 125 Km
2. 100 Km
3. 80 Km
4. 120 Km
Here, the distance travelled by Sourav is constant in both the cases. So, 20 x t = 25 x (t-1) = D =) 20t = 25t – 25 =) 5t = 25 =) t = 5 hrs So, Distance travelled = 20 X 5 = 100 Km.
