​

Answer 1

Answer:

Riju's house is 1.5 km from Abdul's house. Riju's house is 0.8 km from Neha's house. Riju takes 15 minutes to reach Abdul's house and Abdul takes 10 minutes to reach Neha's house. Riju walks faster than Abdul

Explanation:

Distance between Riju's house and Abdul's house = 1.5 km

Distance from Riju's house to Neha's house = 0.8 km

Time taken by Riju to reach Abdul's house = 15 minutes = 1/4 hr

Time taken by Abdul to reach Neha's house = 10 minutes = 1/6 hr

Assuming that Neha's house is in between Riju's and Abdul's house as there is no evident data about the distance of Abdul's and Neha's house.

Therefore,

Distance between Neha's house and Abdul's house = 1.5- 0.8= 0.7 km

The equation for speed = $\frac{Distance}{Time}$

Therefore,

Speed of  Riju  =$\frac{1.5 km}{\frac{1}{4} hr}$=6 $km/hr$

Speed of Abdul = $\frac{0.7 km}{\frac{1}{6}hr }$= 4.2 $km/hr$

Hence Speed of Riju is greater than Abdul and so Riju walks faster than Abdul
