Answers
Given data : Nitan goes to school with a speed of 4 km/hr and return to the village with a speed of 6 km/hr If he takes 3 hour in all.
To find : How far is Nitan's school from his village ?
Solution : according to given data,
⟹ traveling speed for school = 4 km/hr
⟹ traveling speed for village = 6 km/hr
⟹ time taken for whole journey = 3 hour
Let, distance covered by Nitan be x.
Hence, Total distance covered by Nitan is 2x.
Now,
⟹ total speed = total distance /total time taken
⟹ speed of (shcool + village) = 2x/3
⟹ 4 + 6 = 2x/3
⟹ 10 = 2x/3
⟹ 2x = 10 * 3
⟹ 2x = 30
⟹ x = 30/2
⟹ x = 15 km
Answer : Hence, Nitan's school is 15 km far from his village.
