Answer:
x = 97
Step-by-step explanation:
Using Pythagoras' identity on the right triangle
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
x² = 65² + 72² = 4225 + 5184 = 9409 ( take the square root of both sides )
x = = 97
Jason arrives at the factory first
It takes 5 minutes until the other person arrives
<u><em>Solution:</em></u>
<em><u>The time taken is given by formula:</u></em>
<em><u>Jason lives 25 miles away from the factory and drives at 60 miles per hour</u></em>
Therefore, time taken by Jason is:
Convert to minutes
1 hour = 60 minutes
Therefore,
<em><u>Jeremy lives 35 miles away from the factory and drives at 70 miles per hour</u></em>
Therefore time taken by Jeremy is:
They leave their houses at the same time
25 minutes < 30 minutes
Thus Jason arrives first
Jason arrives to the factory in 25 minutes
Jeremy arrives to the factory in 30 minutes
⇒ 30 - 25 = 5 minutes
Jeremy arrives after Jason by 5 minutes
It takes 5 minutes until the other person arrives
