Answer:
- speed of the first bus: 36 2/3 miles per hour
- speed of the second bus: 73 1/3 miles per hour
Step-by-step explanation:
The second bus travels twice as fast, so will take half the time of the first bus. The second bus takes 3 hours less time, so that is half the time of the first bus.
The first bus's speed is (220 mi)/(6 h) = 36 2/3 mph.
The second bus's speed is twice that: 73 1/3 mph.
An aritmetic sequcne is represented as
where
an=nth term
a1=first term
d=common differnce, or how much each term increases by
n=which term
example
1,3,5, etc
first term is 1
common difference is 2 because it increases by 2 each time
so the formula would be
if we had
5,3,1
first term s 5
common difference is -2 since it goes up by -2 each time
so formula is
hope this helps
So if you're driving 25 miles per hour, it would take you 7 hours to drive 175 miles.
175 miles ÷ 25 miles = 7 hours.
Answer:
The expression representing Number of the necklaces after h hours is .
Step-by-step explanation:
Given:
Number of necklaces in the beginning = 20
Number of necklaces made per hour = 4
Number of necklaces to be made = 50
We need to write the expression that represents the number of necklaces we have after h hours.
Solution:
Let the number of hours be denoted by 'h'.
now we can say that;
Number of the necklaces after h hours can be calculated by Number of necklaces in the beginning plus Number of necklaces made per hour multiplied by number of hours.
framing in equation form we get;
Number of the necklaces after h hours =
Hence The expression representing Number of the necklaces after h hours is .
