The ratio between the speeds of two trains is 7 : 8. If the second train runs 400 kms in 4 hours, then the speed of the first train is:

### Answer & Explanation:

Answer: Option D

Explanation: Let the speed of two trains be 7x and 8x km/hr.

Then, 8x = 400/4 = 100

x = 100/8 = 12.5

Speed of first train = (7 x 12.5) km/hr = 87.5 km/hr.

A man on tour travels first 160 km at 64 km/hr and the next 160 km at 80 km/hr. The average speed for the first 320 km of the tour is:

### Answer & Explanation:

Answer: Option C
