Answer 2

Given:

The distance which the train travelled = 135 miles

Time taken to travel = 60 minutes

To find:

The speed attained in this travel.

Solution:

Let $s$ be the distance travelled by train in time $t$ minutes. Then, the speed $v$ attained during this time can be calculated as:

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

$v=\frac{s}{t}$

Here, distance and time are given. Hence, speed can be calculated by substituting the values in the above formula:

$v=\frac{135}{60}$

$v=2.25$

The unit for distance is mentioned in miles and the unit for time is mentioned in minutes. Hence, the unit for the speed of the train is miles per minute.

Thus, $v=2.25miles/minute$

The speed of Acela Express on the route between Boston, Massachusetts, New Haven, and Connecticut is 2.25 miles/minute.
