31.5 miles
If she runs 2.25 miles/day and she runs 14 days, you multiply 14*2.25
A is 69000 I hope you do good on your test/homework
Answer:
Step-by-step explanation:
Let's look at simpler cases. If there was just one visit that would be 124. if there were two, each time he'd have to pay 124 so it's 124+124 = 248. So this is multiplication, because next would be three, which is 124+124+124 or 124 time 3.
In total then it's 124*14. You may usually use an x for multiplication, and if you do just keep in mind * can also be used. or, if something is inside of parenthesis like this 124(14) or (124)14. If you need help doing the multiplication let me know.
Answer:
Step-by-step explanation:
Let the distance the slower hiker travels=d,
the distance the faster hiker travels=15-d (Since, the sum of the distances they walk is 15mi).
Let the speed of the slower hiker in mi/hr=s,
the speed of the faster hiker=s+0.5
Now, equation for the slow hiker:
(1)
and equation for the faster hiker:
(2)
Now, substituting the equation (1) in equation (2),
and 
The speed of the slower hiker is 
and The speed of the faster hiker is 
.
