Paul would like to send a parcel to his friend in ABC country.
The freight charge is $8 per kg per km.
What is the total charge for sending the parcel weighing 12kg for 35km?

The problem is i don't understand the ''per kg per km'' so anyone cares to explain it for me? Thanks

a-Lost-9uY SG

$8 1kg 1km la

MinnieNotMouse SG

oh, ok thanks …

Agenda SG

12 x 8 = AnsA
AnsA x 35 = Final Answer

think thats the answer..

per kg per km means for each kg that travels each km

means if i have 1 kg parcel and if i want to send to your house which is 2km away, using the $8 per kg per km rate. it would cost me $16

i think thats correct.

MinnieNotMouse SG

ohh... ok thanks Smile

X2.Most of the young girls around the age of 12-15 type twittily Laughing

wishboy SG

they twit to cover up for their atrocious spelling mistakes Laughing

anyway, i thought if 8*12, the answer would be for 8 kg 8 km
den times 35 would be 280 kg 280 km ?

hiphop2009 SG

it is a very simple question.

8 to the power of 12 will be too teadious for a pri 6 kid~

^tamago^ SG

12*35/(8* Cool

popikachu SG

$8 per kg per km -->> 1kg 1km is $8
12kg and 35 km -->> how much is 12kg 35km

1kg X 1km = $8
12kg X 35km = $8 X 12 X 35

Or

1kg X 1km = $8
1kg X 35km = $8 x 35
12kg X 35km = $8 X 35 X 12
still the same...

ndmmxiaomayi SG

You won't be surprised if they come up with such questions for PSLE. Anyway, there are some patterns to be explored... know it and you can solve it very fast.

wishboy SG

the sign is * not ^ leh
* = multiply
