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
