Calculate the speed of a car that travels a distance of 2.4km in 2 minutes ​
hammer [34]

Answer:

72 kilometres per hour

Explanation:

The formula for calculating speed is distance/time.

So to work this out you would convert 2 minutes into hours. You would divide 2 by 60 to convert it into hours. This is because the standard unit for speed with kilometres is kilometres per hour. Then  you would divide 2.4 by that.

1)Divide 2 by 60:

2/60=0.0333333

2) Divide 2.4 by 0.0333333.

2.4/0.0333333=72.00007

3) Round it.

72km/h
