Suppose you drive an average of 25 miles a day, for a total of 60 years in a lifetime. The total distance you would have covered

Ahat [919]

The total distance you would have covered is equivalent to going around the earth 22 times.

<h3>Total distance traveled</h3>

The total distance traveled at a given speed and time of motion is calculated as follows;

Distance = speed x time

$Distance = \frac{25 \ miles}{day} \times \frac{365 \ days}{1 \ year} \times 60 \ years\\\\Distance = 547, 500 \ miles$

<h3>Distance round the Earth</h3>

The distance round the earth or circumference of the earth of the earth has been given as 25,000 miles

<h3>Number of times round the earth</h3>

$n = \frac{547,500}{25,000} \\\\ n = 21.9 \ times \ \approx 22 \ times$

Thus, the total distance you would have covered is equivalent to going around the earth 22 times.

Slav-nsk [51]

Answer:

100watts

Explanation:

Given parameters:

Workdone = 500Nm

Time taken = 5s

Unknown:

Power in watts = ?

Solution:

Power is the rate at which work is done;

Power = $\frac{workdone }{time}$

Input the parameters and solve;

Power = $\frac{500}{5}$ = 100watts
