Question

an aeroplane flies 2400km in 3 hours. How many kilometres, will it fly in 7hours​

Answer 1

Step-by-step explanation:

first we can find by unitary method that how much the plane will travel in one hour so you can do this by dividing 2400 km by 3 hours

2400/3

=800km

so by this we can know that the plane will travel 800 km in 1hour

so to find how much the plane will travel in 7 hours we need to multiply 800 kilometres to 7hours

800km×7=5600km
