A toaster oven uses67,500 joules of energy in 45 seconds to toast a piece of bread what is the power of the oven

Tcecarenko [31]

If you simply divide joules by seconds, the answer is in units
of joules/sec (watts) which is exactly what you want.

(67,500 joules) / (45 sec) = 1,500 joules/sec = 1,500 watts

Nancy ran a distance of 5km in 30 minutes. What is her speed in meters(m) per hour)h)

Virty [35]

The speed of Nancy who ran a distance of 5 km in 30 minutes is 10000 meters(m) per hour(h).

<h3>What is the rate of speed?</h3>

The rate of speed is the rate at which the total distance is travelled in the time taken. Rate of speed can be given as,

$s=\dfrac{d}{t}$

Here, (d) is the distance travelled by the object and (t) is the time taken but the object to cover that distance.

Nancy ran a distance of 5 km in 30 minutes. There are 60 minutes in one hour. Thus, the time in hour for which Nancy ran is,

$t=\dfrac{30}{60}\\t=0.5\rm\; hr$

The meters in 5 kilometers is,

$d=5\times1000\\d=5000\rm\; m$

She ran 5000 kilometers in 0.5 hours. Thus, the speed of her is,

$s=\dfrac{5000}{0.5}\\s=10000\rm\; km/hr$

Thus, the speed of Nancy who ran a distance of 5 km in 30 minutes is 10000 meters(m) per hour(h).
