50; 45

10%

Step-by-step explanation:

That's what I think, I'm not sure. The difference is 5. 5 is 10% of 50. so I think the percent change from the first value to the second is 10%. I hope someone else also answers though, since once again, I'm not sure.

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
