Question

After 15 minutes a train has moved 9/2 miles toward its destination. How many miles per minute is the train moving

Answer 1

Answer:

$0.30\frac{miles}{minute}$

Step-by-step explanation:

Let

x-------> the distance in miles

t-------> the time in minutes

we know that

The speed is equal to divide the distance by the time

so

$speed=\frac{x}{y}$

in this problem we have

$x=(9/2)\ miles$

$t=15\ minutes$

substitute

$speed=\frac{(9/2)}{15}$

$speed=\frac{9}{30}=0.30\frac{miles}{minute}$
