Question

The formula for the distance, d, an accelerating car can travel is d = 5.6t square. how many minutes, t, doe the car take to travel 1,814.4 m?

Answer 1

your distance(d) is 1,814.4
1814.4 m = 5.6t square
then you square root 5.6t
$\sqrt{1814.4} = \sqrt{ {5.6t}^{2} }$
the square root eliminates the square
$\sqrt{1814.4} = 5.6t$
you square root 1,814.4 m
$42.6 = 5.6t$
(I rounded 42.6) then divide 42.6 by 5.6
$7.6 = t$
(I rounded 7.6)
