Question

The odometer of a car reads 47470 km when the clock shows 11 am. What is the distance moved by

the car if at 12.00pm the odometer reading has changed to 47520 km? Calculate the speed of car in km/h

during this time.​

Answer 2

Answer:

Distance = 50km

Speed = 50km/hr

Explanation:

Given:-

Initial = 47470km

Final = 47520km.

To Find:

Distance travelled = ?

Speed(km/hr) = ?

Procedure:-

Distance Travelled = Final - initial

>> Distance travelled = 47520km - 47470km

>> Distance travelled = 50km

Time Taken = 12:00 - 11:00

>> Time Taken = 1:00 hr

Calculating Speed:

So, Speed = Distance/time

Speed = 50km/1hr

Speed = 50km/hr

What is momentum ?

The linear momentum of a body is defined as product of mass and velocity.

• Odometer is a device used to measure the distance traveled by vehicle.

• Distance is directly proportional to time².

• If a body travels unequal distance in equal interval of time then it is aid to be non uniform motion.

• If a body travels equal distance in equal interval of time then it is aid to be in uniform motion.

• Instataneous speed is the speed in particular instance of time.
