Answer: 243
Step-by-step explanation:
We have the expression
Note that the expression depends on 3 variables
a, b and c
in this case we want to evaluate the expression for
Then change the variable a by the number 2, the variable b by the number 3 and the variable c by the number 4
So we have
Now simplify the expression
The answer is 243
26.2 / 2 = 189.3 / x
<span>Numerator = distance </span>
<span>Denominator = time </span>
<span>126.2x = (2)(189.3) </span>
<span>126.2x = 378.6 </span>
<span>x = 3 </span>
<span>It will take her 3 hours.
I really hope this helps!
