Nilsa is working on a 60 minute math test. there are 20 questions on the test. if it takes her 20 minutes to complete 12 of the questions, what is the
greatest amount of time on average she can spend on each of the 8 remaining questions? write an inequality too : )

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
