David earns $15 per hour working at a bowling alley. This week, he earned $180, how many hours did he work? Choose the correct equation:

12 hrs

Step-by-step explanation: $15 per hour -> $180/$15 = 12 hours

1 hour = 15$

? = 180$

and we use criss cross.

1 hour×180$ = ?×15$

next we divide both of side by 15$.

then cancl $ by$ and we divide 180 to 15 and

we gain 12 and we add hour

the fainal result is 12 hour.

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
