### My Physics...

Physics is a great trouble for me..and I am stuck in one question...
Please anyone help...

The odometer of a car reads 57321.0 km when the clock shows the time 08:30 AM. What is the distance moved my the car, if at 08:50 AM, the odometer reading has changed to 57336.0 km? Calculate the speed of the car in km/min during this time. Express the speed in km/h also..

### Re: My Physics...

Note that within 20 minutes, the car has travelled 15 km.

Thus, speed of the car = (15/20) km/min = 0.75 km/min.

In an hour, it must go 60 times more than in a minute. So, speed = (0.75*60) km/hr = 45 kmph

### Re: My Physics...

The odometer is a device that keeps track of the total distance a car has travelled in its lifetime.

The odometer reading during 08:30 AM was 57321.0 km.
The odometer reading during 08:50 AM was 57336.0 km.

So, 20 minutes have passed and the car has travelled 15 km. (Subtracting the above two statements)

Do you get up to this much?

### Re: My Physics...

Sorry for my delayed reply.

As you know, Average Speed = Total Distance / Total Time

Thus, Average Speed of the car is (15km/20min) = 0.75km/min = 45km/hr
