#105# miles

#s=d/t#

We are given:

#s=45 " m/h" #

#t=2 1/3 "h"= 7/3 "h"#

To find the distance, #d#:

#s=d/t#

#=>d=st#

#=>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"#
