Question

10
The odometer of a car reads 2000 km at the start
of a top and 2400 km at the end of the trip
To the trip took 8h calculate the average speed
of the car in kmh-1 and ms-1​

Answer 1

Answer:-

• Reading at start=2000km
• Reading at end=2400km

$\\ \sf\longmapsto Total \:Distance\:Travelled=2400-2000$

$\\ \pmb{\sf\longmapsto 400km}$

• Time=8h

We know that

$\boxed{\sf Average \:Speed=\dfrac{Total\:Distance}{Time}}$

$\\ \sf\longmapsto Average\:Speed=\dfrac{400}{8}$

$\\ \sf\longmapsto Average\:Speed=50km/h$

$\\ \pmb{\sf\longmapsto Average\:Speed=50kmh^{-1}}$

$\\ \pmb{\sf\longmapsto Average\:Speed=5000mh^{-1}}$
