$105$ $105$ miles

$s = \frac{d}{t}$ $s=d/t$

We are given:

$s = 45 m/h$ $s=45 " m/h"$

$t = 2 \frac{1}{3} h = \frac{7}{3} h$ $t=2 1/3 "h"= 7/3 "h"$

To find the distance, $d$ $d$ :

$s = \frac{d}{t}$ $s=d/t$

$\Rightarrow d = s t$ $=>d=st$

$\Rightarrow d = 45 m/h \times \frac{7}{3} h$ $=>d=45"m/h" xx 7/3 "h"$

$=>d=cancelcolor(red)(45)^color(blue)(15) "m"/"h" xx 7/cancelcolor(red)(3) "h"$

$=>d=15"m"/cancelcolor(red)("h") xx 7cancelcolor(red)("h")$

$=>d=15 "m" xx 7$

$=>d=105"m"$
