Answer 2

Answer:

The speed of aeroplane is $900$ km/hr.

Step-by-step explanation:

Given : Distance traveled by aeroplane = $1500$ km

          Time taken = $1$ hour $40$ minutes

To find : Speed of an aeroplane ?

Solution :

• It is given that the distance traveled by aeroplane = $1500$ km

          Time taken = $1$ hour $40$ minutes = $60+40=100$ minutes

• We have to find the speed of an aeroplane.
• The speed of any vehicle is given by the ratio of distance to the time.
• The formula of speed is,

       Speed = $\frac{Distance}{Time}$

                  = $\frac{1500}{100}$

                  = $15$ km/hr

• Now, speed in km/hr = $15*60$

                                = $900$ km/hr

• ∴ The speed of aeroplane is $900$ km/hr.
