A student walks a distance of 3km in 20minutes. calculate his average speed

NNADVOKAT [17]

Answer:

9 Km/h

Step-by-step explanation:

Walking 3 Km for 20 minutes from the definition of speed, it's distance covered per unit time. Here, the distance covered is expressed per unit hour.

$Speed=\frac {distance}{time}$

Substituting 3.5 Km for distance and time for 20 minutes

To convert time into hours, we divide the minutes by 60 hence time=20/60=1/3 hours

$Speed=\frac {3 Km}{1/3 hours}=9 Km/h$

Therefore, the speed is 9 Km/h

Seth invested n dollars into an investment fund last year. After a period of one year, the value of his investment can be repres

Crank

Answer: A. The value of his investment decreased by 16% during this time period.

Step-by-step explanation:

Here the initial amount = n

Final amount after 1 years = 0.84n

The total change in the initial amount = n - 0.84n = 0.16 n

$\text{ The percentage change in the initial amount} = \frac{\text{ the total change in initial amount}}{\text{ Initial amount}}\times 100$

= $\frac{0.16 n }{n} \times 100 = 16\%$

Thus, the amount is decreases by 16% in one year,

⇒ Option A is correct.
