Answer:
Step-by-step explanation:
Calculating the average speed during this time interval is the same as calculating how many km he traveled per hour.
This is also the same thing as the unit rate. Do that division and find that he traveled 100 km/hr.
The formula for simple interest is i = p*r*t, where p is the principal, r is the interest rate as a decimal fraction, and t is the time in years.
Here, i = ($315) (0.015) (3) = $14.18 (answer)
S=6
Solution
6/2=3
(6*4)=24
24-21=3
An equivalent expression could be 2.75, 100%+175%, or 300%-25%<span />
