100 3/4 x 75 1/2
25 x 3 x 75 1/2. (Divided by 4 to 100 and 4 to get 25)
25 x 3 x 75 1/2 ( multiple everything on top)
5625/2 ( then divided normally)
2812.5 or 2812 1/2

Given the distance travelled and the time elapsed, the average speed of the train is approximately 1.63 miles per minutes.
<h3>What is the average speed of the train?</h3>
Given that;
- Distance traveled d = 75miles
- Time elapsed t = 46 min
- Average speed s = ?
Average speed = distance traveled / elapsed time
Average speed = 75miles / 46min
Average speed = 1.63 miles per minutes

Answer:
so this uses proportions.
you need to find the side BF which is proportional to the side BF.
You do:
9/6=x/42

9*42=6*x
378=6x
divide by 6 on both sides
x=63
the answer is 63
