Question

An aeroplane flies 1288 km in 1 hour 55 minutes. Find its speed?​

Answer 1

Step-by-step explanation:

We know that, Speed = Distance/Time

Given:-

• Distance = 1288km

• Time = 1hr 55min

=> 1hr 55min = 1 55/60 hr

=> 1hr 55min = 1 11/12

=> 1hr 55min = 23/12hr

Now,

S = D/T

=> S = 1288/23/12

=> S = 1288×12/23

=> S = 672 km/h

Therefore, Speed of Aeroplane = 672km/h. ANS..

Answer 2

Answer:

672 km/hr

Step-by-step explanation:

Given,

distance = 1288 km

time = 1 hr 55 minutes

= 1 55/60

= 1 11/12

= 23/12 hr

Speed = distance/time

= 1288/23/12

= 1288×12/23

= 672 kmph

Therefore,speed of the aeroplane is 672 kmph
