Answer:
b.168
Step-by-step explanation:
<h3>
Answer: 50 mph</h3>
==============================================
Work Shown:
1/10 = 0.1
0.1 mile = 7.2 seconds
1 mile = 72 seconds (multiply both sides by 10)
1/72 mile = 1 second (divide both sides by 72)
3600/72 = 3600 seconds (multiply both sides by 3600)
50 miles = 3600 seconds
50 miles = 1 hour
The car's speed is 50 mph
Note: 1 hour = 60 min = 60*60 = 3600 seconds
Answer:
Maximum distance = 94.6 million miles
Minimum distance = 91.4 million miles
Step-by-step explanation:
The mean distance of the Earth from the sun is 93 million miles.
The distance varies by 1.6 million miles.
The maximum distance of the Earth from the sun is 93 + 1.6 = 94.6 million miles
The minimum distance of the Earth from the sun is 93 - 1.6 = 91.4 million miles.
The final answer is B because you just add all three together. Hope you get it!
