Question

The Melbourne Formula 1 track is 5.303 km in length.

The track record is 1 minute and 24 seconds. What is
the average speed (km/h) for the lap record? Answer
correct to two decimal places.

Answer 1

Explanation:

To calculate the average speed of the lap record, we need to know the distance covered and the time taken.

Distance = 5.303 km

Time = 1 minute and 24 seconds = 84 seconds

To convert seconds to hours, we divide by 3600 (the number of seconds in an hour):

`(84 \: seconds \:)/(3600) = 0.02333 \: hours`

Now we can calculate the average speed:

`Average \: speed = (d)/(t) = (5.303km)/(0.02333)`

Average speed = 227.59 km/h
