The ratio between the speeds of two Bullet trains is 7: 8. If the second Bullet train runs 440 kms in 4 hours, then the speed of the first train is:  Choose the most appropriate option:
A) 89.25 km/hr.	B) 37.25 km/hr.	C) 90.25 km/hr.	D) 94.25 km/hr.	E) 96.25 km/hr.
E   96.25 km/hr.   Let the speed of two bullet trains be 7x and 8x km/hr.   Then, 8x = (440/4)=

<output>55/4 = around 13.75</output>
13.75   Hence, speed of first bullet train= (7 x 13.75) km/hr = 96.25 km/hr.
