Answer:
passenger train is travelling 58mph
freight train at 38 mph
Step-by-step explanation:
first i listed all the numbers that could divide 190
1,2,5,10,19,38
& then it was simple from there .
next all i had to do is add 20 to each number and then see if that number could divide 290
38 could divide 190
38+20 =58
290÷58=5
190 ÷38=5
it took the passenger train 5 mins to travel 290 miles while the freight train took 5 mins to trvel 190 miles

Let's call the length L and the width w.
perimeter = 2L + 2w
44 = 2L + 2w
the length is 6 yards longer than the width. so L = w + 6.
plug this into the equation. 44 = 2(w+6) + 2w
44 = 2w + 12 + 2w
44 = 4w + 12
32 = 4w
w = 8
L = w + 6
L = 8 + 6
L = 14
area = Lw
area = 8(14)
area = 112 yd²
