At its maximum speed, a space shuttle can travel 700m high in 40 seconds. It will also take 5 seconds to pass a point. What then is the length of the space shuttle?	Choose the correct option
A) 50 m B) 75 m C) 100 m D) 125 m E) 150 m
Let the length of the space shuttle be x metres and its speed be y m/sec. Then, x / y = 1 ⇒ y = x / 5   ∴ (x + 700) / 40 = x / 5 ⇔ x = 100 m. Answer 100 m
