<h3>
Answer: 43 km per hour</h3>
==================================================
Work Shown:
total distance = 43+40+46 = 129 km
total time = 1+1+1 = 3 hours
average speed = (total distance)/(total time)
average speed = (129 km)/(3 hrs)
average speed = (129/3) (km/hr)
average speed = 43 km per hour
Answer:
g = - 5
Step-by-step explanation:
2 - 8g = -3 - 9g
Add 9g to both sides of the equation:
2 - 8g + 9g = -3 - 9g + 9g
2 + 1g = - 3
Subtract 2 from both sides of the equation:
2 - 1g - 2 = - 3 - 2
1g = -5
Divide both sides of the equation by 1:

g = -5
S = m+6
(s + 3) = (m + 3)1.5
When solved m=9 and s=15
When plugged in it works.
