Step-by-step explanation:
Answer:
It will take 12 and 30 hours
Step-by-step explanation:
To solve this, you need to divide by <u>distance needed to travel by the speed</u>
600/48 is equal to 12.5 hours.
.5 hours is equal to 30 mins because 60mins times .5 is 30 minutes, therefore <u>the final answer is 12.5 hours</u>
I hope this helps :)

= tanA = right side ⇒ proven
Let n = number of records.
Each record costs $7, so n records cost 7n.
She then spent $3, so the total spent is 3n + 3.
She spent a total of $24, so 3n + 3 must equal 24. That gives us the following equation.
7n + 3 = 24
Subtract 3 from both sides.
7n = 21
Divide both sides by 7.
n = 3
Answer: She bought 3 records.
