There isn't a direct answer to this, but I can show you!
This is how you group Pennies, Nickels, and Dimes.
1 Penny= 1 cent.
1 Nickel= 5 cents.
1 Dime= 10 cents.
Imagine if there was 5 pennies, 3 dimes, and 8 Nickels.
That might seem like a lot of numbers, but it's pretty simple!
You know how pennies are worth 1 cent? If we had 5 pennies, that would be 5 cents.
1+1+1+1+1=5 cents.
Then, we have 3 dimes. Dimes are each 10 cents.
So, 10x3 (If you know multiplication, if not, you will learn it later) :)
10+10+10= 30 cents.
Now, nickels. We have 8 nickels! Remember, each nickel is 5 cents.
5+5+5+5+5+5+5+5=
40 Nickels.
Now add all of the coins up.
5 cents + 30 cents + 40 cents = 75 cents!
I hope this helped! If you need more help, you can ask me. :)
1.53 m/s toward the beach
Explanation:
The magnitude of the velocity of the runner is given by:
where
d is the displacement of the runner
t is the time taken
In this case, d=110 m and t=72 s, so the velocity of the runner is
Velocity is a vector, so it consists of both magnitude and direction: we already calculate the magnitude, while the direction is given by the problem, toward the beach.
