EQUATION

Exercise

Let  x be the total journey time.

If the car has traveled 2/3 of its journey, the equation to solve would be:

\mathsf{\dfrac{2}{3}x = 26}

Now, let's solve it. Multiply both sides by 3:

\mathsf{3\left(\dfrac{2}{3}x\right) = 3(26)}

‏‏‎ ‏‏‎ ‏‏‎ ‏‏‎ ‏‏‎ ‏‏‎ ‏‏‎ ‏‏‎\mathsf{\dfrac{6}{3}x = 78}

‏‏‎ ‏‏‎ ‏‏‎ ‏‏‎ ‏‏‎ ‏‏‎ ‏‏‎ ‏‏‎\mathsf{2x = 78}

Divide both sides by 2:

\mathsf{2x \div 2 = 78 \div 2}

‏‏‎ ‏‏‎ ‏‏‎ ‏‏‎ ‏‏‎ ‏‏‎\large{\boxed{\mathsf{x = 39}}}

‏‏‎ ‏‏‎ ‏‏‎ ‏‏‎ ‏‏‎ ‏‏‎ ‏‏‎

Answer. The entire journey will take 39 minutes.
