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.
