A car skidded m ft during a race. The expression s =   is the rate of speed of the car in ft/s. Find the rate of the speed of the car, if the car skidded 288 ft

---

 

The correct answer is: 48

Here, we have to find the speed of a car when it skidded 288m during a race given that s = √8m.
We have, 
s = √8m
=> s = √(8×288)
=> s = √2304
=> s = 48 ft/s.
Hence, the correct option is D.

 A radical expression is an expression containing a square root.
