Q: How many sec are in 45 min?

Write your answer...

There are 60 sec in one min 35 rev/min x 45/60 = 26.25 revs

1 min = 60 sec 30 min = 1800 sec

1 min = 60 sec Hence 1 sec = 1/60 min

RECORD TIMES- 1. 5 min 3 sec 2.3 45 sec 3.6 7 sec 4.9 15 sec 5.2 47 sec 6.12 32 sec 7.4 min 7 sec 8.6 min 9.3 min and 2 sec 10.30 sec and you beat them

1 min = 60 sec 6 min = 6 x 60 = 360 sec

60 sec = 1 min 60 min = 1 hr 40 sec = 40/60 min = 2/3 min 2 min 40 sec = 22/3 min = 8/3 min → 2 min 40 sec = 8/3 ÷ 60 hr = 8/3 x 1/60 hr = 2/45 hr speed = distance ÷ time = 15/8 mi ÷ (2 min 40 sec) = 13/8 mi ÷ (2/45 hr) = 13/8 x 45/2 mi/h = 585/16 mph = 369/16 mph ≈ 36.5 mph

1 month = 50,400 min, 3,024,000 sec

0.75 min = 45 sec

300 sec

60 sec = 1 min 75.5 sec = 75.5/60 min = about 1.258 min

5 min (60 sec/ 1 min) = 300 sec

(7 min) x (60 sec/min) = 420 sec

32 min 9 sec 40 min 10 sec adding gives... 71 min 19 sec 1 hr 11 min 19 sec. ■

There are 60 min in a Sec. SO ... (127 min)/60 = 2 min 7 sec.

327 seconds.

19.2m/min calculation 60 sec/1 min * 32 cm/sec * 1 m/100cm

1 mi / 45 MPH * 60 min/hr * 60 sec/min = 80 seconds.

There are 60 seconds in a minute, so multiply by 60. 5 min X 60 sec/min = 300 sec.

1/60

45 hours 55 min 49 sec 12mil sec by nathan buccanan

1 min = 60 sec 1 hour = 60 min = 60 × 60 = 3600 sec → 1 sec = 1/3600 hr distance = speed × time = 45 mph × 1 second = 45 mph × 1/3600 hr = 45 × 1/3600 miles = 1/80 mile = 1 chain = 22 yards = 66 feet

2 hour = 3600 sec 5 min = 300 sec total sec in 2hr&5min= 3900
