Question 1128317
If he ran 1 mile each day for 7 days,
{{{ 1*7 = 7 }}} miles/week
-----------------------------
If he ran 1 1/8 miles each day for 7 days,
{{{ ( 1 + 1/8 )*7 = 7 + 7/8 }}} miles/week
-----------------------------
7 gets multiplied by a factor greater than 1,
so the miles/week is greater
