1.What is an average speed of a car that travels a distance of 450 km in 3 hours 40 minutes?
d = r*t
r = d/t
------------------------
2. In what time will a taxi travel a distance of 150km at an average speed of 90km/h?
t = d/r
--------------------------
3. What do you think happens to time when the car is travelling at high speed?
There's no noticeable effect at the speeds cars travel.
There are effects as you approach the speed of light.
