The average rate, in miles per hour, of the rail portion of the trip is; D: 75
<h3>How to calculate the average speed?</h3>
Since exactly 1/3 of the distance travelled was by rail, then we can say that;
(1/3) * (90) = 30 miles
We are told that part of the trip took 1/5 of the travel time. Thus;
Time it takes to travel that distance is:
(1/5) * (2) = 2/5 of an hour
Average rate is;
30/(2/5) = 150/2 = 75 mph

Answer:
C / ( 2 pi) = r
Step-by-step explanation:
C = 2 pi r
Divide each side by 2 pi
C /2 pi= 2 pi r / 2 pi
C / ( 2 pi) = r
