$a=5.43\ m/s^2$

Step-by-step explanation:

Given that,

Initial speed of a vehicle, u = 25 km/hr = 6.95 m/s

Final speed of a vehicle, v = 1200 km/hr = 333.34 m/s

Time, t = 60 s

We need to find the acceleration of the vehicle. It is equal to the rate of change of velocity. It can be given by :

$a=\dfrac{v-u}{t}\\\\a=\dfrac{333.34 -6.95 }{60}\\\\a=5.43\ m/s^2$

So, the acceleration of the vehicle is $5.43\ m/s^2$ .

$25.20

Step-by-step explanation:

The extended warranty on a ceiling fan is 18% of the purchase price.

If the price of the fan is $140,

We have to find the warranty.

Warranty=18% of 140

= $\dfrac{18}{100}\times 140$

= $25.20

Hence, the correct option is:

$25.20
