Question

What is the average speed of a car traveling 980 km in 11 hours

Answer 1

The average speed of the car is equal to the distance covered by the car (S=980 km) divided by the time taken (t=11 h):

`v= (S)/(t)= (980 km)/(11 h)=89.1 km/h`

we can also convert this value into m/s, keeping in mind that

`1 km = 1000 m`

`1h=60\cdot 60 s=3600 s`
So we have

`v=89.1 (km)/(h) \cdot (1000 m/km)/(3600 s/h)=24.75 m/s`
