At the healesville supermarket,
shopping trolleys are 1 metre
long. you work collecting them
and stacking them into an
area. each shopping trolley that
is added to the stack adds on
25 cm. how long would the line
be if you stacked 20 trolleys?

5.75 meters

Step-by-step explanation:

Here we are told that , the trolley added to the stack , increases the length by 25 cms or 0.25 mts.

Hence every trolley stacked will add 0.25 mts to the trolley already stacked. However the first trolley in 20 trolleys will be occupying 1 mt only. Hence , rest of the 19 trolleys will be covering 0.25×19=4.75 mts.

Hence , total distance covered by 20 trolleys =

1+4.75=5.75 mts
