A car drives 494 km in 4 hours 45 minutes what is its average speed in kilometers per hour?

The average speed is 104 kilometer per hour

Solution:

Given that,

A car drives 494 km in 4 hours 45 minutes

To find: Average speed in kilometers per hour

The average speed is given by formula:

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

Thus average speed is:

Thus average speed is 104 kilometer per hour
