Answer: 6 5/7
Step-by-step explanation:
The surface 5 cm, and the length is 10 cm
Outbound Trip 120 miles 60 mph equals 2 hours
Return Trip 120 miles
Total Trip 240 miles at 45 mph average speed
Total time = distance / rate = 240 / 45 = 5.3333333333 Hours
The return trip of 120 miles takes (5.3333333333 Hours MINUS 2 hours)
Return Trip Speed = 120 / 3.333333333 = 36 miles per hour
13+8n=-3
<em>Subtract 13 from both sides</em>
8n=-16
<em>Divide both sides by 8</em>
n=-2
