Jermaine has entered a bowling tournament. To prepare, he bowls five games each day and writes down the score of each game,
along with the mean of five scores. He is looking at the scores from one day last week and finds that one of the numbers has
accidentally been erased.
The four remaining scores are 259, 272, 218, and 237. The mean score of the five games is 254. What is the missing score?

The answer is in the photo. I can only upload it to file hosting. link below.

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
