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

Step-by-step explanation:
Answer: it will take 0.25 years for these trees to be the same height.
Step-by-step explanation:
Let x represent the number of years that it will take these trees to be the same height.
Type A tree is 5 feet tall and grows at a rate of 13 inches per year. This means that the total height of Type A tree after x years would be
13x + 5
Type B tree is 3 feet tall and grows at a rate of 21 inches per year. This means that the total height of Type B tree after x years would be
21x + 3
For both trees to be of the same height, the number of years would be
13x + 5 = 21x + 3
21x - 13x = 5 - 3
8x = 2
x = 2/8 = 0.25
