Answer:
v = 72 km/h
Step-by-step explanation:
Given that,
The distance covered by the Patrick, d = 288 km
Time taken, t = 4 hours
We need to find the average speed of Patrick. We know that the average speed of an object is equal to the total distance covered divided by total time taken. Let it is v. So,
So, his average speed is equal to 72 km/h.
To solve this we can make it into an equation, which looks like this
y = 2x (for Rebecca)
y = x + 10 (for Alice)
The we subtract one equation from the other to solve
0 = x - 10
10 = x
x = 10
Now we replace x in whichever equation and we get 20
So, each girl will read 20 books for them to be at the same book.
