Question

a train travels 400 km in 2 hour and 320 km in 4 hour find the ratio of their speeds ​

Answer 1

Answer:

Distance traveled by Train in 2 hours = 400 km

Distance traveled by Train in 1 hours d = 400/2 = 200 km

Distance traveled by Train in 4 hours =320 km

Distance traveled by Train in 1 hours D = 320/4 = 80 km

Now,  

The required ratio = d : D = 200 : 80 = Now reduce it........
