Two spaceships are observed from Earth to be approaching each other along a straight line. Ship A moves at 0.620c relative to the Earth observer, and ship B moves at 0.500c relative to the same observer. What speed does the captain of ship A report for the speed of ship B?

Two spaceships approach each other, each moving with the same speed as measured by an observer on Earth positioned directly between them. If one ship measures the other to be moving at a speed 0.7c, what is the speed of each ship as measured by the Earth observer?

A man on the moon sees two spacectaft, $A$ and $B$, coming toward him from opposite directions at the respective speeds of $0.800 c$ and $0.900 c$. (a) What does a man on $A$ measure for the speed with which he is approaching the moon? For the speed with which he is approaching $B ?(b)$ What does a man on $\ddot{B}$ measure for the speed with which he is approaching the moon? For the speed with which he is approaching $A$ ?
