Answer:
s = 71 mph, and s+9 = f = 80 mph
Step-by-step explanation:
The distances the two busses travel add up to 604 mi.
Letting f be the faster speed and s the slower. Then f = s + 9 (mph).
Then (s + 9)(mph)(4 hr) + (s)(mph)(4 hr) = 604 mi. Solve this for s:
4s + 36 + 4s = 604 mi, or 8s = 568. Finally, s = 71 mph, and s+9 = f = 80 mph.

Answer:
0.56457
Step-by-step explanation:
log 3 with base 7 = (Log 3)/ (Log 7) = 0.47712125 / 0.845098040014
(Log 3) / (Log 7) = 0.56457
