A girl was born 35 years after her mum what fraction of her mum's age would a girl be at age 15​

3/10

Step-by-step explanation:

mom = 35 when girl is born

girl = 0 when born

after 15 year

mom = 35 + 15 = 50

girl = 0 + 15 = 15

fraction = girl / mom = 15/50 = 3/10

3/10 or 30%

Step-by-step explanation:

So the mom was 35 when she had her kid. When the kid is 15, that would make the mom 50 (35+15).

Then just divide! The term "fraction" is just a confusing term that most of the time means to divide.

15/50 is 3/10. If you want it as a percentage, then multiply the whole thing by 10/10, which gives you 30/100, or 30% of her mom's age. Hope this helped!

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
