Answer: (3) 280 km
Explanation:-
Let be the distance covered by the first train = X km
And distance covered by second train = (X + 20) km
Then ,
X/130 = (X + 20)/150
by cross multiplication,
150X = 130X + 130 x 20
150X – 130X = 2600
20X = 2600
X = 2600/20
X  = 130 km
Total distance = X + X + 20 = 130 + 130 + 20
= 280 km
Hence, the answer is (3) 280 km.
