Answer:
2000 meters
Step-by-step explanation:
From the above question
Total time = 15 minutes
Converting minutes to seconds
1 minute = 60 sec
15 minutes = x
Cross Multiply
x = 60 × 15 = 900 seconds
Hence, 900 seconds = Total time
Total time = Time to the marker + Time from the marker
From the question, we are given the Speed to the marker = 5 m/s
Speed from the marker = 4 m/s
Time = Distance/speed
Let the distance be represented by x
Hence:
x/4 + x/5 =900
Multiply all through equation by Lowest Common Denominator = 20
5x + 4x= 900×20
9x = 900 ×20
Divide both sides by 9
9x/9 = 900 × 20/9
x = 2000 meters
Therefore, the total distance to the marker = 2000 meters

Answer:
3n^2+n-2
Step-by-step explanation:
Coefficient is the number that we multiply an expression that contains a variable. In all the expressions above the variable is n.
Some examples:
Coefficient of n^2 is 1.
Coefficient of n in n^2+2n+1 is 2.
Solution:
In 5n^2+6n-1 the Coefficient of n is 6.
In 2n^2+5n+1 the Coefficient of n is 5.
In 40^2 - n +9 the Coefficient of n is - 1.
In 3n^2 +n - 2 the Coefficient of n is POSITIVE 1.
We tend to not write 1*n because 1*n=n.
