I’m on khan academy(6th grade math) and i’m confused so here’s the question
“ hanna is recovering hundreds of treasure chests from an ancient shipwreck. she is able to recover 8 chest every 4 hours
complete the table using equivalent ratios.”
the table is:
8 chests every 4 hours
12 chests every 6 hours
10 chests every _(blank)_ hours
so yea i did the middle one myself but i’m stuck on the last one

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

y=x+9
