Answer:
58 km/h
Step-by-step explanation:
Let s represent James's speed. Then s-24 is Kim's speed. The relationship between time, speed, and distance is ...
d = st
Since the two were traveling in opposite directions, their distance apart is the sum of the distances they drove. James drove for 1.6 more hours than the 1.8 hours Kim drove, so their total distance is ...
(1.6 +1.8)s +1.8(s -24) = 258.4
5.2s -43.2 = 258.4 . . . . . . . . . . . . collect terms
5.2s = 301.6 . . . . . . . . . . . add 43.2
s = 58 . . . . . . . . . . . divide by 5.2
James drove at 58 km/h.
