Question
A car skidded m ft during a race. The expression s = is the r rate of speed of the car in ft/s. Find the rate of the speed of the car, if the car skidded 169 ft
Hint:
Speed = Distance/ time.
The correct answer is:
We have to find the speed of a car which skidded 169m during a race given that speed is a function of distance skidded, s = √8m.
We have, s = √8m
=> s = √8×169
=> s = 2×13√2
=> s = 26√2.
Hence, the correct option is C.
A radical expression is an expression containing a square root.
