A four-wheel-drive vehicle is transporting an injured hiker to the hospital from a point that is 30 km from the nearest point on

zepelin [54]

Answer:

$D=200\ km$

Explanation:

distance on terrain, $d_t=30\ km$

distance on the road, $d_r=70\ km$

speed on terrain, $v_t=30\ km.hr^{-1}$

speed on road, $v_r=130\ km.hr^{-1}$

time taken on the terrain,

$t_t=\frac{d_t}{v_t}$

$t_t=\frac{30}{30}$

$t_t=1\ hr$

time taken to cover the distance on the road:

$t_r=\frac{d_r}{v_r}$

$t_r=\frac{70}{130}$

$t_r=\frac{7}{13}\ hr$

Now the distance covered on terrain in the total time:

$D= v_r\times (t_r+t_t)$

$D= 130\times (\frac{7}{13}+1)$

$D=130\times \frac{20}{13}\$

$D=200\ km$

is the distance the vehicle must target on the road to minimize the time taken in going off the road.
