21.6 meters per hour
Solve by dividing 54 by 2.5
<em>40</em>
- Step-by-step explanation:
<em>2 + 10 = 24</em>
<em>2(2 + 10) = 2×12 = 24</em>
<em>3 + 6 = 27</em>
<em>3(3 + 6) = 3×9 = 27</em>
<em>7 + 2 = 63</em>
<em>7(7 + 2) = 7×9 = 63</em>
<em>5 + 3 = 40</em>
<em>5(5 + 3) = 5×8 = 40</em>
For a triangle 30-60-90,
If shorter leg is x, then hypotenuse is 2x.
So, if shorter leg is 4,
then hypotenuse is 2*4 = 8.
Answer is 8.
