TS EAMCET 7 May 2018 Shift 1 Solved Paper

Let the distance travelled by the rains be d .
Case(A)
The time required to pass each other is,
t=

d

v1+v2

4=

d

v1+v2

d=4(v1+v2) …… (I)
Case (B)
Speed of A increased 50% .
The time required to pass each other is,
t=

d

( 150 100 )v1+v2

3=

d

1.5v1+v2

Substitute the value of d in the above equation.
3=

4(v1+v2)

1.5v1+v2

4.5v1+3v2=4v1+4v2
0.5v1=1v2

v1

v2
