Question

The ratio between the speeds of two trains is $7:8$. If the second train runs $440$kms in $4$hours, then the speed of the first train is:

• A. $47.4$ km/hr
• B. $57.19$ km/hr
• C. $48.13$ km/hr
• D. $96.25$ km/hr 

Answer 1

Let assume first train speed 7x and second 8x
8x=440/4
x=13.75

Now,7*13.75= 96.25 km/hr.
