Hello!

❖ 8.5 in = 425 miles
If 1 mi = 50 inches, multiply by 8.5:
50 x 8.5 = 425

The answer is D. All the opposite sides are congruent.
Let a,b,c,d and e are five numbers
mean = (a +b+ c+ d+e)/5 = 30
⇒ (a +b+ c+ d+e) = 150_______(1)
now, Let the number excluded be a
then, new mean = (b+ c+ d+e)/4 = 28
⇒ (b+ c+ d+e)= 112
putting this value in (1),
⇒a + 112 = 150
⇒a = 150 -112 = 38
excluded number = 38
