Q102-105

Abhay, Bhalu, Chandu, Damu, Ebrahim, Faizal, Gayatri and Hari are Ram's friends. The above diagram gives the distance of each of their houses and time taken by Ram to visit each of them.

A dark circle represents the Distance of particular person's house from Ram's house (Scale 1 division = 1.75 km).

A dark square represents the Time taken by Ram to reach a particular person's house starting from his house (Scale division = 1.2 hrs.)

      Question 103

      How much time will Ram take to reach Chandu's house, if he travels at the speed at which he travels to Hari's house

      Solution

      While going to Hari's house

      The distance is $$2.5\times1.75=4.375$$ km

      The time taken is $$4\times1.2=4.8$$ hours

      Average speed = $$\dfrac{4.375}{4.8}=0.911$$ kmph

      While going to Chandu's house

      The distance is $$4.5\times1.75=4.375$$ km

      As the distance and speed is same as that while going to Hari's house, the time taken will also be the same.

      Hence, the time taken is 4.8 h.
