Final answer:

The car will skid 48 m at 144 km/h with locked brakes.

Step-by-step explanation:

To find the distance the car will skid at 144 km/h, we can use the concept of proportionality. We can set up a ratio with the speed and distance of the first scenario (48 km/h and 16 m) and the unknown distance at 144 km/h. Using the ratio:

48 km/h / 16 m = 144 km/h / x

Cross multiplying gives us:

48 km/h * x = 16 m * 144 km/h

Simplifying the equation gives us:

x = (16 m * 144 km/h) / 48 km/h

x = 48 m

Therefore, the car will skid 48 m at 144 km/h with locked brakes.
