HI I JUST DID THE FIRST ONE . SORRY I CAN'T ANSWER THE 5TH AND6th IT'S HARD
<h3>Given that it is arithmetic</h3>
Answer:
2.9 mi
Step-by-step explanation:
The time difference t between 12.30pm and 3.30pm is 3h.
Let the distance to Marat's house be s.
The equation to calculate velocity v is given by:
v = distance / time.
Now you can write an equation for the time difference t and use the two velocities and the 90 min(= 1.5h) she stays:
3 = s/12 + 1.5 + s/2.3
Solve this equation for s:
(1/12 + 10/23)* s = 1.5
s = 2.9
13/20,3/5,29/50,14/25,53/100
