The relationship between speed (s), distance (d), and time (t) is s = d/t. Substituting the given information, we see that 105/t < 70105 < 70t1.5 < t So, the time will be AT LEAST 1.5 hours. Hope this helps.
The possible values of x are 3 and 7
<h3>Solving rational expressions</h3>
Given the rational expression below;
√60-8x = x - 9
Square both sides to have:
(60-8x)² = (x-9)²
60-8x = x²-18x+81
Equate to zero to have;
x²-18x+81 - 60 + 8x = 0
x² - 10x + 21 = 0
x² -3x-7x +21 = 0
x(x-3)-7(x-3) = 0
x = 3 and 7
Hence the possible values of x are 3 and 7
