Answer:

90/1.5=60 mph

Step-by-step explanation:

I assume that the train is traveling at constant speed.

Between 12:45 pm and 2:15 pm the train has traveled 180-90=90 miles. So 90 miles in 1.5 hours which means that its speed is 90/1.5=60 mph

faust18 [17]

Answer:

12

Step-by-step explanation:


The sum of the measures of the interior angles is given by:


(n-2)*180\\


n:sides of the polygon


And in a convex polygon the sum of the exterior angles sums 360°


Then


(n-2)*180=5*(360)


You just solve it and the answer is 12.
