Answer:
25%
Step-by-step explanation:
I don't know if you meant profit or markup but,
take the difference of $80 & $50 = $30
What percent of 50 is 30? It's 3/5 or 60%. So there is a 60% markup on the original price of 50$.
The answer is 360 miles since he can drive 60 miles per hour so just multiply 60x6 and your answer is 360
