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

15x>200. The minimum number of hours he must work to earn at least $200 is 14 hours. Working 14 hours will allow him to receive $210. This is the minimum number of hours he can work because if he works 13 hours instead, he will only make $195, which is less than 200. 15x>200 (15x is equal to or greater than 200) x=14.
