Sure:
90 year old parents : 60 year old children (had kids at 30; very reasonable)
60 year old parents : 40 year old children (had kids at 20; unlikly but possible)
45 year old parents : 30 year old children (had kids at 15; very unlikly but not impossible)
Set them equal to each other then solve for X
Answer: 2.4×10^5
Step-by-step explanation:
30×8×10^3
First multiply and forget about ×10^3 for now:
30×8 = 240
Then add back the ×10^3:
240×10^3
Then simplify:
2.4×10^5
To check the answer:
30×8×10³=
30×8000= 240000
Then simplify:
240000 = 2.4 ×10⁵
<span>d = miles from the airport to home.
2.1*d+5=49.10 solve for d
d=</span>49.10-5/2.1 = 21 miles
