Answer:
of the distance
Step-by-step explanation:
We know that a ferry traveled 
of the distance between two ports in 
hours.
In order to calculate what fraction of the distance between the two ports can the ferry travel in one hour we can do the following reasoning :
The rate of the ferry is the same at any time.
The ferry will travel of the distance in hours.
If we divide each fraction by 3 ⇒
and 
We do this to obtain a ''1'' in the numerator of the second fraction (the hours fraction). Now, we can say that :
The ferry will travel 
of the distance in 
hours.
Finally, we multiply each fraction by 7 (in order to obtain the distance for 1 hour) ⇒
and 
We found out that the ferry will travel of the distance in 1 hour.
Answer:
a = 2 m/s²
Step-by-step explanation:
where v is the final velocity, u is the initial velocity, and t is the time it takes. the intial velocity is always 0 m/s. given the equation, we subsitute:
a = 10m/s ÷ 5s
a = 2 m/s²

no it does not

5-3=2
Answer:
4 coins
Step-by-step explanation:
First, let's find out how much she gave the teller:
2($20)=$40
Now, let's find out how much change the teller owes her:
$40.00-$39.63=$0.37 or 37 cents
The largest coin (under 37 cents), is a quarter which is worth 25 cents...
37-25=12 cents
The largest coin (under 12 cents), is a dime which is worth 10 cents...
12-10=2
The largest coin (under 2 cents), is a penny which is worth 1 cent...
2-1=1
And one more penny...
1-1=0
Therefore the fewest amount of coins she can get in change are a quarter, a dime, and two pennies, which is 4 coins.
