Question

Rearrange the following equation

Answer 1

$\\ \sf\longmapsto 5.5\Delta t=1.2\Delta t^2$

• Cancel Del t from both sides

$\\ \sf\longmapsto 5.5=1.2t^2$

$\\ \sf\longmapsto t^2=\dfrac{5.5}{1.2}=4.58$

$\\ \sf\longmapsto t=2.14$

Answer 2

$5.5∆t = 1.2∆t {}^{2}$

• Cancel delta from both sides

$5.5t = 1.2t {}^{2}$

$t {}^{2} = \frac{5.5}{1.2}$

$t {}^{2} = 4.28 \\ t = \sqrt{4.28} \\ t = 2.14$
