=> 0.75 h

It asked speed.

As we know ,

Speed = Distance / Time

Here ,

Distance = 510 km

Time = 0.75 h

Speed = 510/0.75

=> 680 km/h

Answer 2

Given:

Travel distance- 510km

Time - 45 minutes

To Find:

speed.

Solution

Travel distance- 510km

Time - 45 minutes

The unit for time is used either in seconds or hours. since the distance is in kilometres, time should be in hours.

dividing the time in minutes by 60 so we can get the value of time in hours.

$time = \frac{45}{60}$

$time = 0.75hrs$

The formula for speed is

$speed = \frac{distance}{time}$

adding the values:

$speed = \frac{510km}{0.75hrs}$

$speed = 680km/hr$

Therefore the speed of the aeroplane is 680km/hr
