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
Answer:
B
Step-by-step explanation:
the best way to do this is to plug in the answers
1. 26+6 < 32
32<32 that is not true so it is not A
2. 0+6<48
yes that is true B is correct
3. 4+6<-40
nope not true its not C
4. 16+6<32
22<32 not true
