The equation can be used to find the time it took student to hike the trail will be 3t= 5(3-t)
What is the equation?
A mathematical statement consisting of an equal symbol between two algebraic expressions with the same value is known as an equation.
The formula for the distance for the to and fro motion is;
x= v × t
The total time required for to and fro motion is;
[tex]\rm t_1 + t_ 2 = 3 \\\\ \frac{x}{v_)1} +\frac{x}{v_2}=3 \\\\ \frac{x}{3} +\frac{x}{5}= 3 \\\\ x = \frac{45}{8} \\\\ x = 3 \times \frac{15}{8} \\\\\ x =v \times \frac{15}{8} \\\\ x = v \times t[/tex]
From the equation B;
3t= 5(3-t)
3t=15-5t
8t=15
t=15/8
The equation can be used to find the time it took Stu to hike the trail will be 3t= 5(3-t)
Hence option B is correct.
