luna would take? seconds to travel exactly 210 feet.

Explanation:

Step1: Identify given variables

Steven's distance formula: $y = 10.5x$, where $y$ = distance (ft), $x$ = time (sec). Target $y=210$.

Step2: Substitute $y=210$ into formula

$210 = 10.5x$

Step3: Solve for $x$

$x = \frac{210}{10.5}$
