|Longship Logic problem |[pic] |

| | |

|Dawn, Mark, Josh and Tina are have been experimenting with homemade Viking longships. |Don’t forget to answer the question. |

|[pic] |Use the table below to show how long each person’s Longship was in the air. |

|After launching their longship, they timed how long they took to sail along across a pond . | |

|The times they recorded were: |Name |

| |Longship time |

|4.56s, 6.01s, 5.67s and 7.66s but not in that order. | |

| |Dawn |

|How long did each child’s longship take to cross the pond? | |

| | |

|Clues |Mark |

|Dawn's longship took longer to cross than Josh's. | |

|The longship that took 6.01s belonged to a boy. | |

|Josh noticed that his longship's time was made up of three consecutive digits. |Tina |

|Tina said, "The digits of my Longship's time add up to 15." | |

| | |

| |Josh |

|Abbie, Ben, Carly and Declan are four more children in the same class. |[pic] |

| |Don’t forget to answer the question. |

|[pic] |Use the table below to show how long each person’s Longship was in the air. |

|Abbie Ben Carly Declan | |

| |Name |

|After launching their longships, they timed how long they took to cross the pond. |Longship time |

|The times they recorded were: | |

| |Abbie |

|8.31s, 6.78s, 5.73s and 3.48s but not in that order. | |

| | |

|How long did each child's Longship take to cross the pond? |Ben |

| | |

|Clues | |

| |Carly |

|The longship which took the longest belonged to a girl. | |

|The time Ben's longship took to cross had an 8 digit. | |

|Carly said, "The digits of my longship's time add up to 15." |Declan |

|Declan's longship took longer to cross than Ben's | |

| | |

|Abbie, Ben, Carly and Declan and Emily are five more children in the same class. |[pic] |

|[pic] |Don’t forget to answer the question. |

|Abbie Ben Carly Declan Emily |Use the table below to show how long each person’s Longship was in the air. |

|Emily said, "My best friend and I both have a 6 digit in our times." | |

|Declan's longship took longer than Carly's longship. | |

|The longship which took nearly 7 seconds to cross belonged to a boy. |Declan |

|Ben's longship took less than half as long as Abbie's to cross. | |
