Question

(e) An aeroplane flies 1000 km in 1 hour 40 minutes. Find its speed.​

Answer 1

Step-by-step explanation:

Speed = 1000/100 × 60

= 600 km/hr

Answer 2

Answer:

Step-by-step explanation: distance covered by aeroplane = 1000km

time = 1h 40min

so speed = 600km/h

time in hours = 1 + 40/60 h

                     = (1+4/6) h

speed = distance/time

         = 1000/1+4/6

         =1000/10/6

         = 1000*6/10

         =6*100

         = 600km/h
