Reggie and Alvin and Jose are member of a relay running team Reggie finish his leg of the race 2.4 five seconds faster than Alvi
1 answer:
The time taken by Reggie for his leg of the race is 57.12 seconds.
Alvin is 2.45 seconds slower than Reggie. Therefore, time taken by Alvin for his leg of the race is:
seconds
We also know that Jose is faster than Reggie by 3.81 seconds. Therefore, time taken by Jose for his leg of the race will be:
seconds
Thus, the total time for the team will be the sum of the times taken by Reggie, Alvin and Jose for their respective legs.
Therefore, total time for the team is: seconds

Answer:
If Length is decreased by 10% then it would become a square.
Step-by-step explanation:
Given:
Area of Rectangular field = 1440 sq. m
Perimeter = 152 m.
We need to find which one needs to be decreased by what percentage to make it a square.
Solution:
Let length be denoted by 'l'.
Also Let width be denoted by 'w'.
Now we know that Area of rectangular field is given by Length times width.
framing in equation form we get;
Also we know that Perimeter of rectangular field is given by 2 times sum of Length and width.
framing in equation form we get;
Now Substituting equation 2 in equation 1 we get;
Now we will find the root by factorizing the same we get;
Now solving for each to find the value of 'w' we get;
So We can say that;
Width = 36 m and Length = 40 m
Now we need to find out of length or breadth which one is to be decreased by what percentage to make it a square.
We know that square has all sides same.
So from the data we found we can say that if length is decreased by 4 then length and breadth(width) both will be equal.
So to find percentage decreased we will divide length to be decreased by total length and then multiply by 100.
framing in equation form we get;
percentage decreased =
Hence If Length is decreased by 10% then it would become a square.
