The average speed, in km/minute, of the train is 2.79 km/minute
<h3>Calculating average speed </h3>
From the question, we are to calculate the average speed in km/minute
From the given information,
Distance travelled = 503 km
Time taken = 3 hours = 3 × 60 minutes = 180 minutes
Using the average speed formula,
Average speed = Distance / Time
∴ Average speed of the train = 503 / 180
Average speed of the train = 2.79 km/minute
Hence, the average speed, in km/minute, of the train is 2.79 km/minute

Answer:
x=18
Step-by-step explanation:
Hey There!
So if you did not know all of the angles in a triangle will add up to equal 180
So we use the equation
180=2x+3x+5x
and solve for x
step 1 combine like terms
2x+3x=5x
5x+5x=10x
so now we have
180=10x
step 2 divide each side by 10
180/10=18
therefore x = 18
