A car traveling at a speed of 70km/h is overtaken by a tractor traveling at 25km/h. The driver of the car needs a toilet and knows that it will take him 3 minutes. How many kilometers does the car have to cover, so the tractor does not overtake it?

Correct answer:

s =  1.9444 km

Step-by-step explanation:

v1=70 km/h v2=25 km/h  t=3 min h=3:60  h=0.05 h  s1=s2  v2 (x+t)=v1 x 25 (x+0.05)=70 x  45x=1.25  x=451.25=0.02777778  x=3610.027778  s1=v2 (x+t)=25 (0.0278+0.05)=18351.9444 km s2=v1 x=70 0.0278=18351.9444 km  s=s1=1.9444=1.9444 km
