Answer : The duration of the loan is, 6 months
Step-by-step explanation :
First we have to determine the discounted money.
Discounted money = $850 - $800 = $50
Thus, interest = $50
Now we have to determine the time of loan.
Formula used :

where,
P = principle
R = interest rate
T = time
S.I = simple interest
Now put all the given values in the above formula, we get:
For 1 year : 
For 12 months : 

Thus, the duration of the loan is, 6 months
Answer:
3 miles per hour
Step-by-step explanation:
We know that distance over time, d/t, is equal to rate, r.
By knowing this, we can substitute in the distance and time given into the formula:
d/t = r
15/5 = r
To solve this, we just need to simplify 15/5 to give us our answer:
15/5 = r
3 = r
This means that our rate is 3 miles per hour.
