Let x be the number of hours she jogs, and y be the number of hours she bikes.
The total time would then be x + y = 5
The total distance (based on the given speeds) would be 6x + 12y = 50
Multiply the first equation by 6 to get 6x + 6y = 30
Subtract this from the second equation to get 6y = 20
y = 10/3 or 3 1/3
Substitute this value back into the first equation to get x = 5/3 or 1 2/3
Therefore, Yolanda will have to jog 1 2/3 hours and bike 3 1/3 hours.

The inequality is: 5>x≥0
Step-by-step explanation:
We have to write the inequality one by one
The inequality symbols are used to write inequalities.
So,
5 is greater than x will be written as:
5>x
And
0 is less than or equals to x:
0≤x or x≥0
We have to combine the both inequalities so that the variable is not repeated. The inequality symbols have to be written carefully while writing the compound inequalities.
5>x≥0
