Method $2$: Use R function $`$predict$()`$to predict.

$```\{$r$\}$

# code to predict distance for a speed at $19$ mph$.$

predict$($model$,$ newdata $=$ data.frame$($speed $=19))$

#TYPE $25$ AFTER THE LAST EQUAL SIGN IN ORDER TO ANSWER QUESTION $24$

predict$($model$,$ newdata $=$ data.frame$($speed $=25))$

$```$

$24.$ Predict the distance taken to stop with speed of cars at $25$ mph using R output.
