The average speed is 104 kilometer per hour
<em><u>Solution:</u></em>
Given that,
A car drives 494 km in 4 hours 45 minutes
To find: Average speed in kilometers per hour
<em><u>The average speed is given by formula:</u></em>
From given,
Distance = 494 km
Time = 4 hours 45 minutes
We know that,
1 hour = 60 minutes
Therefore,
Thus,
time = 4 hours 45 minutes = 4 hour + 0.75 hour = 4.75 hour
<em><u>Thus average speed is:</u></em>
Thus average speed is 104 kilometer per hour
