Answer:
The speed of the second friend is 12 km/h
Step-by-step explanation:
Let the speed of the second friend be x km/h.
In 1 hour, the second friend travels x km
In 3 hours, the second friend travels 3x km
In 3hours, the first friend travels 3×10 km
= 30 km
So, 3x - 30 = 6
or, 3(x- 10)= 6
or, x-10 = 2
or, x = 12
The speed of the second friend is 12km/h
