We have to find x and x is the hypotenuse. We use this formula:
hyp²=side²+side²
So:
hyp²=side²+side²
hyp²= 12²+9²
hyp²= 225
hyp²= √225
hyp= 15
Therefore, the hypotenuse is 15 and x is 15.

His new time compared with the old time was increased by factor of 2
<h3>Further explanation</h3>Acceleration is rate of change of velocity.
<em>a = acceleration (m / s²)v = final velocity (m / s)</em>
<em>u = initial velocity (m / s)</em>
<em>t = time taken (s)</em>
<em>d = distance (m)</em>
Let us now tackle the problem!
This problem is about Kinematics.
In this problem we assume that the unicorn is moving at a constant speed so that the acceleration is zero.
<u>Given:</u>
first distance = d₁ = 50 miles
second distance = d₂ = 300 miles
v₂ = 3 v₁
<u>Unknown:</u>
t₂ : t₁ = ?
<u>Solution:</u>
To find his new time , we will use the following formula.
