Suppose that P and Q are points on the number line.
If PQ = 12 and P lies at -15, where could Q be located?
If there is more than one location, separate them with commas.

I think Q would be at positive 3

Step-by-step explanation:

If PQ= 12 and P= -15

the difference is 3

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
