Question

Sumit walks 1 km 2 hm and Kevin walks 1 km 5 hm everyday. Who walks longer and by how much?

Answer 1

Answer:

hope it helps

pls mark me brainliest

Step-by-step explanation:

we know that 1hm = 100m

so

2hm = 200m and 5hm = 500m

1km= 1000m

so

sumit walks = 1km 2hm = 1000m + 200m = 1200m

Kelvin walks = 1km 5hm = 1500m

clearly, kelwin walks longer than sumit

by how much= 1500 - 1200 = 300m

Answer 2

Answer:

please mark me as BRAINLIST

Step-by-step explanation:

9kilometre=9km

1hecto metre=0.1km⇒5hecto metre=0.5km

1Deca metre=0.01km⇒6Deca metre=0.06km

1metre=0.001km⇒4metre=0.004km

∴9km+5hm+6dam+4m

=9+0.5+0.06+0.004=9.564km

9.564km÷12=0.797‬‬km
