Answer:
It will take them 5 hours to meet if they start moving towards eachother simultaneusly.
Step-by-step explanation:
Distance, s = 540 miles
Motocycle's speed, v = 48 mph
Time for motorcycle to cover 48 miles, t = 
=
= 11.25 h
For a car it takes 2.25 hours less than 11.25 for motorcycle:
Time for car than becomes: 11.25 - 2.25 = 9 h
Speed for car would be v(c) = 
=
= 60 mph
<em>For finding when they will meet, we will need relative speed: </em>
Since they are moving towards each other the relative speed is the sum of speed of car and the speed of motorcycle
Relative Speed = 48 + 60 = 108 mph
Distance = 540 miles
Time = 
= 
= 5 hours
It is already in radical form......... but, if you want us to make it into exponential form, it is 8x^(2/3)
Answer:
4(2n-5)
Step-by-step explanation:
So we know Valerie has 5 less than double the number of brad's books. Brad has n books, so make that 2n to double it.
Because she has 5 less than that, the expression is now 2n-5. The is the total of Valerie's books.
We know that Brad has 4 times the number of Valerie's books, so just multiply that expression by 4.
The final answer is 4(2n-5).
You're welcome. :)
