Q: Answer- Harsh covers a certain distance with his own speed, but when he reduces his speed by 20 km/hr his...

Let distance be x km and speed be y kmhr xy - 20 - xy 80 x 4yy - 20 .............1 xy - xy 10 20 x 2yy 10 ..............2 From 1 and 2, we get 4yy - 20 2yy 10 2y - 40 y 10 y 50 kmhr Then x 2 50 50 10 100 60 6000 km

but when he reduces his speed by 20 km/hr his time duration for the journey increases by 80 hrs, while if he increases his speed by 10km/hr from his original speed he takes 20hrs less than the original time taken. What is the distance covered by him?

A 6000km

B 1500km

C 3000km

D 2000km

E 4500km
