An aeroplane takes off from Delhi to Lucknow. It took 13/5 hours to complete the flight. From Lucknow it further flew to Mumbai and landed there in 9/7 hours. Fow how much time did the aeroplane flew ?​

Answer 1

We have,

• Aeroplane started it journey from delhi and landed in lucknow, it took 13/5 hours
• Futher on, from lucknow it flew to mumbai and landed in 9/7

So, the total time the aeroplane flew will be the sum of time taken in reaching lucknow & mumbai;

• Total time = Time taken to reach lucknow + time taken to reach mumbai

= Total time = 13/5 + 9/7

= Total time = 91 + 45/35

= Total time = 136/35

= Total time = 3 hours 31 minutes

Therefore, the total time aeroplane flew is 136/35 hours or 3 hours 31 minutes.
