Let the relative speed will be given by:
38/4=9.5 km/h
Let the speed of the first tourist be x km/h
the speed of the second one is (9.5-x) km/h
distance covered by the first one is:
4*x+2=4x+2 km
distance covered by the second one is:
(9.5-x)4 km
=(38+4x) km
total distance will be given by:
(38+4x)+(4x+2)=38
40+8x=38
8x=-2
x=-1/4 km/h
this mean that he was traveling in the opposite direct thus the speed was 1/4 km/k
The speed of the second one will be:
9.5-1/4=9.25 km/h
I think the answer to that question is illuminate confirmed.
Answer:
Option (d)
Step-by-step explanation:
Given,
y" +y=sin x ...........(1)
The particular solution




Putting the value of y" and y in equation (1)


Therefore 2A =0 -2B=1
⇒A=0 
Therefore
