Given:
Speed of train = 85 miles per hour
Total distance = 102 miles
To find:
The time taken by train to cover 102 miles.
Solution:
We know that,
[tex]Speed=\dfrac{Distance}{Time}[/tex]
On substituting the values, we get
[tex]85=\dfrac{102}{Time}[/tex]
[tex]Time=\dfrac{102}{85}[/tex]
[tex]Time=1.2[/tex]
Therefore, the time taken by train to cover 102 miles is 1.2 hours.
