The blood alcohol content (BAC) for a male is estimated by $B A C = \frac{10 N - 7.5 H}{6.8 M}$ , where $N$ is the number of standard drinks, $H$ the hours since drinking began and $M$ the mass in kg. Find the BAC for a 80 kg male who had 5 standard drinks over 3 hours, correct to three decimal places.

Solve $\frac{3 x - 4}{5} = 7$ .

Example 3 · 2 marks · numerical answer

The stopping distance of a car is $d = v t + \frac{v ^{2}}{2 a}$ , where $v$ is the speed in m/s, $t = 1.5$ s is the reaction time and $a = 7$ m/s² is the deceleration. Find the stopping distance for a car travelling at 60 km/h, correct to 1 decimal place.
