Answer:
63 miles per hour
Explanation:
The first second of the trip, speed can be found by taking 110 miles and divide by 2 which means for the first half, the speed was 55 miles per hour
To find the speed of the second half you must first figure out the distance travelled. To do this you take the total distance (299) and minus the distance traveled in the first section (110) to get the total of 189 miles.
Since the trip all together was 5 hours and the first portion took 2 hours. The second portion took 3 hours. To find the speed you must divide 189 by 3 which is 63 miles per hour
