Three cities A, B, and C are equidistance from each other. A car travels from A to B at 60 km/hr, from B to C at 40 km/hr from C to A 50 km/hr determine the Average speed:

\(\frac{1}{{\frac{1}{3}\left( {60 + 40 + 50} \right)}}\)

\(\frac{1}{{\frac{1}{3}\left( {\frac{1}{{60}} + \frac{1}{{40}} + \frac{1}{{50}}} \right)}}\)

\(\frac{1}{3}\left( {\frac{1}{{60}} + \frac{1}{{40}} + \frac{1}{{50}}} \right)\)

1.	Three cities A, B, and C are equidistance from each other. A car travels from A to B at 60 km/hr, from B to C at 40 km/hr from C to A 50 km/hr determine the Average speed:
A.	\(\frac{1}{{\frac{1}{3}\left( {\frac{1}{{60}} + \frac{1}{{40}} + \frac{1}{{50}}} \right)}}\)
B.	\(\frac{1}{{\frac{1}{3}\left( {60 + 40 + 50} \right)}}\)
C.	\(\frac{1}{3}\left( {\frac{1}{{60}} + \frac{1}{{40}} + \frac{1}{{50}}} \right)\)
D.	\(\frac{3}{{60 + 40 + 50}}\)
Answer» B. \(\frac{1}{{\frac{1}{3}\left( {60 + 40 + 50} \right)}}\)
