Question 1097258

Tuna swim at steady speed of 9 miles per hour they never stop during their entire lives how many hours does it take a tuna to swim 216 miles
<pre>{{{matrix(1,9, D, "=", S, "*", T, "=====>", T, "=", D/S)}}}
Substitute 9 for S, and 216 for D to get: {{{matrix(1,3, T, "=", 216/9)}}}
Calculate it!
