Step-by-step explanation:
Answer: 252
Step-by-step explanation:
You just multiply 84 by two and then ad another 84.
If the required difference is 600 mi, lets start of counting by 10s and multiplying the current number
800-700 = 100
1600-1400 = 200
2400-2100 = 300
3200-2800 = 400
4000-3500 = 500
4800-4200 = 600
if 60 hours pass, they will be 600 miles away from each other.
counting by 10 each time will help with problems like or similar to this.
The answer is D. because if you do 57.75 divided by 5.5 you get 10.5 mi/h
hope this helps :)
