The value of a square root 86 is between 9 and 9.5
<h2><u>Given</u> : - </h2>
x = 2 & z = 3x
<h2><u>Solution</u> : - </h2>
<h3>⇒x + 4z - 5 - 3x</h3>
<h3>⇒(2) + 4(6) - 5 - 3(2)</h3>
<h3>⇒2 + 24 - 5 - 6</h3>
<h3>⇒26 - 11</h3>
<h3>⇒15</h3>
You need to know the distance between the two cities, to use the formula distance = velocity * time from which you solve time = distance / velocity.

That is about 2 hours and 18.5 minutes.
Answer: 2.3 hours
