Here is a question I have. I am chuffed to bits by this.

Lines 1 and 4 are parallel.

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

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.
