In this item, we are asked to split the numerical value which is 54 pounds such that the ratio of the numbers will be 5:4.
To answer, let 5x be the first number and 4x be the second number. With the given scenario, the equation that would best represent the given will be,
54 = 5x + 4x
The value of x is 6 giving us the values of 5x and 4x as 30 and 24, respectively.
Hence, the split will be 30 and 24.
<u>Answer</u>
Incorrect
<u>Explanation</u>
Unpack the problem:
Let the distance round the track to be X.
Speed is the ratio of distance to time.
Robert run a distance of (1/2)x
Elaine run a distance of (3/4)x
Make a plan:
Finding the speed of each.
Compare their speeds to determine who ran faster than who.
Solution:
Robert's speed =(1/2)x/(5/6)
=1/2×6/5x
= (3/5)x
= 0.6x
Elaine's speed = (3/4)x/(9/10)
= (3/4)×(10/9)x
= (5/6)x
= 0.83333x
<em>Elaine ran faster than Robert. </em>
<u>Look back and explain:</u>
0.83333x > 0.6x
Elaine's speed is higher than Robert's speed.
This shows that Elaine ran faster than Robert.
