If I travelled 210 km by car and the trip lasted 3 hours and 12 minutes, what is the average speed of my car?

Given that travelled a distance of 210 km in 3 hours 12 minutes by car  

To find the average speed of the car

Solution:

Distance travelled = 210 km

Time = 3 hours 12 minutes

= $3 \frac{12}{60} = 3 \frac{1}{5} = 3.2$ hours

Average speed of car = $\frac{Distance}{Time}$

= $\frac{210 km}{3.2 hr}$

= $65.63$ kmph

The average speed of car = $65.63$ kmph
