1.	Two persons, 27 km apart, setting out at the same time aretogether in 9 hours if they walk in the same direction, but in 3 hours29.if they walk ia opposite directions: find their rates of walking.
Answer» Let a = the walking rate of the 1st person which is the fastest walker let b = the walking rate of the 2nd person Given9(a - b) = 27(walking the same direction) 3(a + b) = 27(walking in opposite directions)on simplifying a-b=3a+b=9 Solving, 2a = 12a = 12/2 a = 6 km/hr, 1st person's ratethen 6 + b = 9b = 3 km/hr, 2nd person's rateLike if you find it useful

Answer»

Let a = the walking rate of the 1st person which is the fastest walker

let b = the walking rate of the 2nd person

Given9(a - b) = 27(walking the same direction)

3(a + b) = 27(walking in opposite directions)on simplifying

a-b=3a+b=9

Solving,

2a = 12a = 12/2

a = 6 km/hr, 1st person's ratethen

6 + b = 9b = 3 km/hr, 2nd person's rateLike if you find it useful
