Question

1) aeroplane flies 1200 km in 1 bour 20 minutes. Find its speed
2) dog is walking at a speed of 5 km/hr. How much distance will cover in
12 minutes? Please answer step by step​

Answer 1

Step-by-step explanation:

1=)distance=1200 km

=1200×1000

=1200000 m

time= 1 hour 20 min

=1×60+20

=80 min

=80×60

=4800sec

speed =. distance /time

=1200000/4800

=250 m /sec.

2)

speed=5km/hr

time taken= 12 min

=12/60 hr

=1/5 hr

atq

speed = dis./time

therefore.

dis.= speed × time

dis=5 km/hr×1/5hr

dis.=1 km answer.

Answer 2

Step-by-step explanation:

1).

• Distance traveled=1200km
• =1200000m
• Time=1hour20min
• 1×60+20
• 80min
• 4800sec

speed=distance /time

speed=1200000/4800

speed=250 m/s

2)

• speed=5km/h
• time=12minute=12/60
• Distance=speed×time
• Distance=5×12/60
• Distance=60/60
• Distance=1km
