b) 3 h 20 min expressed in seconds
c) 0.59 km expressed in cm
d) 380 km expressed in cm
e) 0.592 mg expressed in grams
f) 25 g expressed in micrograms
g) 36 km/h expressed in m/s
Answers
Answer:
a) 3.5 dm = 350mm
sol:as 1dm = 100 mm
so, 3.5dm =3.5×100
=350mm
b) 3h 20m = 200min
sol: as 1h =60 min so,3h = 180 min
3h 20m = 180+20=200min
c) 0.59 km = 59,000 cm
sol: 1km = 100000cm
so , 0.59km =0.59×100000
=59000 cm
d) 380km = 38,000,000cm
380km = 38,000,000cm sol: 1km= 100000cm
so,380km=380×100000
=38000000cm
e)0.592mg = 0.000592 g
sol: 1g = 1000mg
1mg = 1/1000g
so, 0.592mg=0.592/1000
= 0.000592g
f) 25g = 25,000,000microgram
sol : 1g = 1,000,000 microgram
so, 25g =25×1000000
= 25000000microgram
e) 36 km/h = 10 m/s
sol: 1 km/h =5/18 m/s
so, 36 km/h = 36×5/18 = 2×5
= 10 m/s
Hope this will help you :)
