Explanation:
9 miles every week. and that for 52 weeks.
how do we calculate how many miles that are ?
well, one basic approach is
9 miles
9 miles
9 miles
... 52 times adding 9 miles.
in math we have a shortcut for that : we multiply. the hint is already in the "times" expression. we take 9 miles 52 times.
9 × 52 = 468 miles
