3*40 + x / 4 = 45.
The answer of x comes out to be 60. Which means that the speed was travel around 60 miles per hour in the last one hour of the total journey.
Well to understand how i constructed its equation is very simple. I equated the total average speeds answer to 45 and just calculated the average speeds with the help of algebra where x is the number of miles..
Answer:
7
Step-by-step explanation:
3.2 -9x+ 7.1 -3x
= (-9x -3x)+ (3.2+ 7.1) (combine like terms)
= -12x+ 10.3
The final answer is -12x+ 10.3~
g(7-h) +3
Now g = 5 and h=2, So lets plug the values
5(7-2) +3
= 5(5) +3
= 25 + 3
= 28
Given :
A train travels 110 miles per hour.
To Find :
How fast does the train travel in feet per second.
Solution :
We know, 1 mile = 5280 feet .
1 hour = 3600 s.
So, speed in feet per second is :
Hence, this is the required solution.
