#0.0335# #(km)/h#

We need to convert #75# #(mi)/h# into #(km)/h#

Cancel the hours in the denominator

#rarr75 (mi)/h*(1h)/(3600s)#

(as #1# hour is #3600s#)

#rarr75 (mi)/cancelh*cancel(1h)/(3600s)#

#rarr75 (mi)/(3600s)#

Cancel the miles in the numerator

#rarr75 (mi)/(3600s)*(1.609km)/(1m)#

(as #1# mile is #1.609km#)

#rarr75 cancel(mi)/(3600s)*(1.609km)/cancel(1mi)#

#rarr75 (1.609km)/(3600s)#

#color(green)(rArr0.0335(km)/s#
