Answer:
total number of sheep in the farm = 28 6 = 168
Step-by-step explanation:
i) let the number of all sheep in the farm be x.
ii) 28 sheep were tagged.
iii) 18 sheep were observed and 3 were found to be tagged.
Therefore the ratio of tagged to sheep to the number of sheep observed
=
iv) therefore we can apply the ratio found in iii) as follows
∴ total number of sheep in the farm = 28 6 = 168
Answer:
<em>Equation: 10t=400</em>
<em>It will take them 40 hours to be 400 miles apart.</em>
Step-by-step explanation:
<u>Constant Speed Motion</u>
If the speed of an object is v, the distance traveled in a time t is:
Ms. Ironperson travels at 50t (not speed, but a distance), and Mr. Thoro travels at 60t. Since the latter travels faster, the distance between them at time t is given by:
To be 400 miles apart, we set the equation:
10t=400
Solving:
t=400/10=40
It will take them 40 hours to be 400 miles apart.
Note: Some assumptions were made in this question:
- The rates are not speeds but distances
- The distances are in miles
