The ratio between the speeds of two trains is 2 : 5. If the first train runs 350 km in 5 hours, then the sum of the speed (in km/h) of both the trains is:
Let the speed of two trains be 2p and 5p respectively
Speed of first train = $$\frac{\ 350}{5}$$ = 70 km/hr
$$=$$> 2p = 70
$$=$$> p = 35
$$\therefore\ $$Sum of the speed of both trains = 2p+5p = 7p = 7(35) = 245 km/hr
Hence, the correct answer is Option C
