Answer:

1.) 5h 35 min

2.) 2 min 33 sec

3.) 8h 38 min

4.) 6h 25 min 1 sec

5.) 5h 54 min 55 sec

Story sums:

1.) The bus journey on March 3rd lasted 6 hours 20 minutes.

2.) Mrs.Roy tends to her garden 15 more minutes then Mrs.Pathak everyday.

3.) The workers worked 5 hours 10 minutes on Tuesday.

Step-by-step explanation:

1.) 10h 20 min - 4h 45 min

10h 20 min

10h*60=600 min

600 min + 20 min = 620 min

4h 45 min

4h*60=240 min

240 min + 45 min = 285

620 min - 285 min = 335 min

335 min/ 60 = 5r35

5h 35 min

2.) 10 min 20 sec - 7 min 47 sec

10 min 20 sec

10 min * 60 = 600 sec

600 sec + 20 sec = 620 sec

7 min 47 sec

7 min * 60 = 420 sec

420 sec + 47 sec = 467 sec

620 sec - 467 sec = 153 sec

153 sec/60 = 2r33

2 min 33 sec

3.) 15 h 22 min - 6 h 44 min

15h 22 min

15 h * 60 = 900 min

900 min + 22 min = 922 min

6h 44 min

6h * 60= 360 min

360 min + 44 min = 404 min

922 min - 404 min = 518 min

518 min / 60 = 8r38

8h 38 min

4.) 14 h 41 min 10 sec - 8h 16 min 9 sec

14h 41 min 10 sec

14h * 60 = 840 min

840 min * 60 = 50400 sec

41 min * 60 = 2460 sec

50400 sec + 2460 sec + 10 sec= 52870 sec

8h 16 min 9 sec

8h * 60 = 480 min

480 min * 60=  28800 sec

16 min * 60=  960 sec

28800 sec + 960 sec + 9 sec = 29769 sec

52870 sec - 29769 sec = 23101 sec

23101 sec/ 60 = 385r1

385 min 1 sec

385 min/ 60 = 6r25

6h 25 min 1 sec

5.) 11 h 10 min 15 sec - 5 h 15 min 20 sec

11h * 60 = 660 min

660 min * 60 = 39600 sec

10 min * 60 = 600 sec

39600 sec + 600 sec + 15 sec = 40215 sec

5h * 60 = 300 min

300 min * 60 = 18000 sec

15 min * 60= 900 sec

18000 sec + 900 sec + 20 sec = 18920 sec

40215 sec - 18920 sec = 21295 sec

21295 sec/60 = 354r55

354 min 33 sec

354 min / 60 = 5r54

5h 54 min 55 sec

Solve these story sums:

1.) A tourist bus takes 4 hours 50 minutes to reach Agra from Delhi. However on 3rd March it broke down on the way and took 1 hour 30 minutes longer.

What was the duration of the journey on 3 march?

4h 50 min + 1h 30 min

4h * 60 = 240 min

240 min + 50 min = 290 min

1h 30 min

1h * 60 = 60 min

60 min + 30 min = 90 min

290 min + 90 min = 380 min

380 min/ 60 = 6r 20

6h 20 min

The bus journey on March 3rd lasted 6 hours 20 minutes.

2.) Mrs Roy tends to her Garden everyday for 1 hour 10 minutes. Mrs Pathak does the same for 55 minutes. How much more time does Mrs Roy spend looking of the garden?

1h 10 min - 55 min

1h * 60 = 60 min

60 min + 10 min = 70 min

70 min - 55 min = 15 min

Mrs.Roy tends to her garden 15 more minutes then Mrs.Pathak everyday.

3.) The workers in a factory worked 3 h 20 min 8 sec less on Tuesday then on Monday. If they work for 8 ho 30 min 50 sec on Monday, for how long they work on Tuesday?

8h 30 min 50 sec - 3h 20 min 8 sec

8h * 60 = 480 min

480 min * 60 = 28800 sec

30 min * 60 = 1800 sec

28800 sec + 1800 sec + 8 sec = 30608 sec

3h * 60 = 180 min

180 min * 60 = 10800 sec

20 min * 60 = 1200 sec

10800 sec + 1200 sec + 8 sec = 12008 sec

30608 sec - 12008 sec = 18600 sec

18600 sec / 60 = 310

310 min / 60 = 5r10

5h 10 min

The workers worked 5 hours 10 minutes on Tuesday.
