Answer:
1 hour and 30 minutes
Step-by-step explanation:
because it took an hour for 10 mile so add another five miles and it would take 30 minutes
Ok so our original fraction is:

To simplify this fraction, look for instances where the values on the top and bottom can be reduced:
For example, 36 over 6 is the same as 6 over 1, so we can simplify the fraction so it is:

We can also eliminate the denominator by dividing the nominator by x^9 so:


And that is the simplified answer of the fraction

Step-by-step explanation:
y=6+4x, as equation (iii)
=> -5x-(6+4x)=21
=> -5x-6-4x=21
=> -5x-4x-6=21
=> -9x-6=21
=> -9x=21+6
=> -9x=27
x= -3, by dividing both sides by -9
So, by inserting x in the first equation,
=> -4(-3)+y=6
=> 12+y=6
=> y=6-12
=> y= -6.
Therefore, x= -3 and y= -6
