We know that

<span>It takes Jonas ---------> 7 1/4 minutes to run the mile
7 1/4-------> (7*4+1)/4------> 29/4 minutes

</span>It takes Mario ---------> 8 5/12 minutes to run the mile
8 5/12-------> (8*12+5)/12------> 101/12 minutes

multiply (29/4) by (3/3)-------> 87/12

[101/12]-[87/12]------> 14/12 -------> 7/6 -------> 1 1/6 minutes

the answer is
1 1/6 minutes

78.8 rounded to the nearest tenths is 78.8

We can not round it to the tenths because it already is rounded to the tenths.
