Question

plz tell me answer very simple question ​

Answer 1

2hr 20min

= 1hr+1hr+20min

= 1hr+60min+20min

= 1hr+55min+25min

Since the advertisement is of 25mins therefore

the total runtime of the magic show is (1hr+55min+25min)-(25min) viz, 1hr 55min.

Answer 2

Total time taken by the show is 2h 20 minutes
2h20min= 2*60+20= 140min

Time for the ad =25 Minutes
Therefore the time taken by magic show = 140-25 mins =138 mins
