Question

A milometer shos the following reading at the start of the journey:389km what wil the reading be when the car has travelled 10km

Answer 1

It is given that the total distance travelled by the car is 2400 km-2000 km = 400 km, that is, 400000 m  and the total time taken =8 hours, that is, 8×60×60=28800seconds..

Average speed in km/hr = total distance/total time = 400/8 = 50 km/hr.

Average speed in m/s = total distance/total time = 400000/28800 = 13.89 m/s.  

Answer 2

Answer:

The reading when car will cover $10km$ is $399km$.

Step-by-step explanation:

It is given that the initial reading at the start of the journey is $389km$.

The car has travelled $10km$.

We need to determine the reading at the end of the journey.

It is determined using the addition of distance.

The reading will be $389+10=399km$

Hence, the reading at the end of journey is $399km$.
