Answer:
8 1/6 < x < 20.5.
Step-by-step explanation:
Use the Triangle Inequality Theorem which states that the sum of any 2 sides of a triangle is always greater that the third side.
So for triangle to be formed:
4x + 2x - 4 > 45
6x > 49
x > 8 1/6.
Also 2x - 4 + 45 > 4x
41 > 2x
2x < 41
x < 20.5.
112.5 seconds per lap. As you need to convert the minutes to seconds, 7 x 60 = 420 + 30 = 450
450/4 = 112.5
