Question

A train travels from Washington DC to new york(225 miles). The train departs at 4:55 PM and arrives in New York at 7:55 PM. What is the average speed of the train in miles per hour?

Answer 1

The average speed is:

`\var{v}=75\: miles/h`

Explanation:

The average speed equation is given by:

`\var{v}=(\Delta x)/(\Delta t)`

Were:

• Δx is the displacement (225 miles)
• Δt is the change in time (3 hours)

Then we have:

`\var{v}=(225)/(3)`

`\var{v}=75\: miles/h`

I hope it helps you!
