Explanation:


We shall solve in miles ("mi.") per hour ("h");  denoted as "mi / h" ; or sometimes, "mph".


Given 26 mi / 4.5 h ; we want to solve for the number of miles (mi) per unit hour (h),

The answer is (26/ 4.5) mi / h l 

26 ÷ 4.5 = 5.7777777777777778→       Round to:  5.778 mi/ h;
                                                                → or;  write as:  5  ⁷/₉ mi /h
