Question

If distance travelled by a train in 495 km in 4 hours 30 minutes.what its speed

Answer 1

speed =distance/time
distance=495km
time=4.5 hours
speed=495/4.5
=4950/45
110km/hr is the answer.

Answer 2

Answer:

110 km/hour

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 = $\frac{30}{60} =0.5$   hours

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

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

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

$Speed =110$

Thus the speed of the train is 110 km/hour
