The velocity of car 2 from the frame of reference of car 1 will be 10 mph.
The change of distance with respect to time is defined as speed. Speed is a scalar quantity. It is a time-based component. Its unit is m/sec.
The given data in the problem is
The velocity of car 1, V₁ = 20 mph south
The velocity of car 2, V₂ = 30 mph north
From the frame of reference of car 1, the velocity of car 2 will be V₁₂
From the frame of reference of car 1, the velocity of car 2 will be;
V₁₂=V₂ - V₁
V₁₂= 30 mph - 20 mph
V₁₂= 10 mph
Hence, the velocity of car 2 from the frame of reference of car 1 will be 10 mph.
