Question

( 50 points ) A train travels at an average speed of 80 km/h. How long will it take the train to travel 320 km?

Answer 1

4 hours

Step-by-step explanation:

`\text{Speed} =\frac{\text{distance} }{\text{time} }`

Then

`\text{time} =\frac{\text{distance} }{\text{speed} }`

Then

`\text{time} =\frac{\text{320} }{\text{80} } =4`

Answer 2

4 hours

Step-by-step explanation:

`\sf time = (distance)/(speed)`

Here the units are same for both, so no need of conversion.

Solve:

time taken = distance/speed

time taken = 320/80

time taken = 4 hours
