Question

A construction crew has just finished building a road. The crew worked for 14.4 days. If they built 3.5 kilometers of road each day, find the total length of road they built

Answer 1

`\sf Hello!`

•
`\sf Length \:of\: road \:built\: each\: day = 3.5 \:km`
•
`\sf Total\: number \:of\: days\: the\: crew\: worked = 14.4 \:Days`


`\sf Then,`


`\sf Total\: length \:of \:road \:bulit` :

=
`\sf No. \:of \:days \:crew \:worked × Length \:of \:road\: built \:each\: day`

=
`\sf 14.4 × 3.5 \:kilometers`

=
`\sf 50.4 \:kilometers`

Answer 2

50.4 kilometer

Explanation:

Given: A construction crew has just finished building a road. The crew worked for 14.4 days. If they built 3.5 kilometers of road each day.

To Find: the total length of road they built.

Solution:

The number of days construction crew worked
`=14.4`
`\text{days}`

kilometers of road built by construction everyday
`=3.5`
`\text{kilometer}`

Now,

Total length of road built by construction road by crew

`(\text{number of days construction crew worked})*(\text{kilometer of road built everyday})`

On putting values,

`14.4*3.5`

`50.4`
`\text{kilometer}`

Therefore, Total length of road built by construction crew in
`14.4`
`\text{days}` is
`50.4`
`\text{kilometer}`
