A car follows a slow moving truck (travelling at a speed of $10$ m/s) on a two-lane two-way highway. The car reduces its speed to $10$ m/s and follows the truck maintaining a distance of $16$m from the truck. On fining a clear gap in the opposite traffic ...

Peak Hour Factor (PHF) is used to represent the proportion of peak sub-hourly traffic flow within the peak hour. If $15$-minute sub-hours are considered, the theoretically possible range of PHF will be $0$ to $1.0$ $0.25$ to $0.75$ $0.25$ to $1.0$ $0.5$ to $1.0$

An aircraft approaches the threshold of a runway strip at a speed of $200$ km/h. The pilot decelerates the aircraft at a rate of $1.697 \: m/s^2$ and takes $18 \: s$ to exit the runway strip. If the deceleration after exciting the runway is $1 \: m/s^2$, then the distance (in m, up to one decimal place) of the gate position from the location of exit on the runway is _______
