Answer:
Following are the solution to the given question:
Step-by-step explanation:
For question 1:
Calculating the speed between A and B:
[tex]Time\ (t)= 1 \ hours\\\\Distance\ (d)= 10 \ km\\\\V=\frac{d}{t}=\frac{10}{1}= 10 \ kmph[/tex]
For question 2:
Calculating the speed between B and C:
[tex]Time\ (t)= (2-1)=1 \ hours\\\\Distance\ (d)= (15-10)= 5\ km\\\\V=\frac{d}{t}=\frac{5}{1}= 5 \ kmph\\[/tex]
For question 3:
In this the speed between A and B is the double to speed between B and C.
