Question

3. Express each of the following as indicated.
a 3.5 dm expressed in mm
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​

Answer 1

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 :)
