Question

in a game of tug of war your team changes -1 3/10 feet in position every 10 seconds. What is your change in position after 30 seconds?

Answer 1

Change in position after 30 seconds will be
`- (26)/(10)`

Explanation:

Given:

Change on position in every 10 seconds =
`-1 (3)/(10)`

To Find:

Change in position after 30 seconds = ?

Solution:

For every 10 seconds the team changes a distance of
`-1 (3)/(10)` feet

After first 10 seconds

The change in position will be
`-1 (3)/(10)` feet =
`-(13)/(10)`

After next 10 seconds i.e., after 20 seconds

The change in position will be =
`- (13)/(10)` +
`- (13)/(10)`

=>
`- (26)/(10)`

After next 10 seconds i.e., after 30 seconds

The change in position will be =
`- (26)/(10)` +
`- (13)/(10)`

=>
`- (39)/(10)`
