Answer:
Elena's running speed is 5 miles/hour
Explanation:
The speed is defined as the covered distance per unit time
In the problem, we have:
The distance covered is the length (circumference) of the circular track which is given as of a mile.
We are also given that she completes each lap (she completes of a mile) in of an hour
To get her speed, we will divide the distance covered by the time taken to cover this distance
This is done as follows:
speed = miles/hour
This means that:
Elena can run 5 miles each hour
Its 5 because you have to change 28 into a fraction by putting a one under like so 28/1
I hope you actually want to know the number of fishes caught by Trenton the friend of Princeton. Let us write down all the details that are given in the question. These details will help in answering the question.
Number of fishes caught by Princeton = 42
Let us assume the number of fishes caught by Trenton = x
Then
70x/100 = 42
7x/10 = 42
7x = 42 * 10
7x = 420
x = 420/7
= 60
So the number of fishes caught by Trenton = 60.
