Presumably the question should have been something like "How many pennies can be placed side-by-side to make up a length of 1 kilometre".
Unfortunately, many countries use a penny as a currency unit and they are not the same size. So there cannot be a definitive answer.
One kilometre is 100,000 centimetres
240 pennies in one sovereign
1,000,000
100,000 pennies
A penny is 3/4 of an inch tall, and this is assuming that you are laying the pennies flat on the ground, top to bottom. A kilometer is roughly 40 million inches, so a simple mathematical equation can be used to figure it out. One kilometer of pennies will thus be roughly worth about $524,934.38
One kilometre is 100,000 centimetres
0.6214 miles = 1 kilometre.
There are 307,087.5 pennies in one ton of pennies
There are 1000 metres in one kilometre so there must be 500 metres in half a kilometre.
240 pennies in one sovereign
0.758 of a kilometre (1,000 metres in one kilometre)
1,000,000
2.7654885612321449
6,100 pennies
One kilometre is equal to 1000 metres. There are 0.9144 metres in one yard. Therefore, rounded to two decimal places, one kilometre is equal to 1000/0.9144 = 1093.61 yards.
100,000 pennies
A thousand of them.
