The average speed is 104 kilometer per hour
<em><u>Solution:</u></em>
Given that,
A car drives 494 km in 4 hours 45 minutes
To find: Average speed in kilometers per hour
<em><u>The average speed is given by formula:</u></em>
From given,
Distance = 494 km
Time = 4 hours 45 minutes
We know that,
1 hour = 60 minutes
Therefore,
Thus,
time = 4 hours 45 minutes = 4 hour + 0.75 hour = 4.75 hour
<em><u>Thus average speed is:</u></em>
Thus average speed is 104 kilometer per hour
Answer: First.
Step-by-step explanation:
Let's find the speed of the first airplane:
2800 ÷ 5 = 560 (miles per hour)
Let's find the speed of the second plane:
3885 ÷ 7 = 555 (miles per hour)
Thus, the first plane flies faster than the second.
Step-by-step explanation:
-x^2+6x+55=0
x^2-6x-55=0
x^2-6x+(3)^2-55-(3)^2=0
(x-3)^2-64=0
Answer:
0.72 is the same as 72100 (try putting both into a calculator!) as you can view 1.00 as 11 . Reducing the fraction gives you 72100 = 1825 .
<em>a(n) = 3/5</em>
I'm sorry if this is not what you're expecting. But that equation says that
the value of the term doesn't depend on where it is in the sequence ...
on 'n' .
Every term is the same number. No matter what 'n' may be, the value of
a(n) is always 3/5.
The first five, fifty, five hundred, or five thousand terms are all 3/5 .
