Answer 2

Step-by-step explanation:

Distance traveled by train = 495 km

Time taken by train = 4 hours 30 minutes

60 minute = 1 hour

So, 1 minute = 1/60 hours

So, 30 minutes = \frac{30}{60} =0.5

60

30

=0.5 hours

So, time taken by train = 4 hours +0.5 hours = 4.5 hours

Speed = \frac{Distance}{Time}Speed=

Time

Distance

Speed = \frac{495}{4.5}Speed=

4.5

495

Speed =110Speed=110

Thus the speed of the train is 110 km/hour
