1.	A Takes 2 Hours More Than B To Walk D Km. If A Doubles His Speed Then He Can Make It In 1 Hour Less Than B. How Much Time Does B Require For Walking D Km?
Answer» SUPPOSE B takes x hours to walk d km Then A takes (x+2) hours to walk d km With double of the SPEED. A will TAKE ½(x+2)hours THEREFORE, x -1/2(x+2) = 1 2x –(x+2) X =4 Hence B takes 4 hours to walk d km. Suppose B takes x hours to walk d km Then A takes (x+2) hours to walk d km With double of the speed. A will take ½(x+2)hours Therefore, x -1/2(x+2) = 1 2x –(x+2) X =4 Hence B takes 4 hours to walk d km.

Answer»

SUPPOSE B takes x hours to walk d km

Then A takes (x+2) hours to walk d km

With double of the SPEED.

A will TAKE ½(x+2)hours

THEREFORE, x -1/2(x+2) = 1

2x –(x+2)

X =4

Hence B takes 4 hours to walk d km.

Suppose B takes x hours to walk d km

Then A takes (x+2) hours to walk d km

With double of the speed.

A will take ½(x+2)hours

Therefore, x -1/2(x+2) = 1

2x –(x+2)

X =4

Hence B takes 4 hours to walk d km.
