A scuba diver is practicing. He begins 3 feet below sea level the surface of the water and then dives down to the 9 foot marker. How far did he dive?

Question

Please answer my question 

Answer 1

6 feet

 

 

total distance =  | ending measure - starting measure |

 

                   =  | -9   -  -3 |

 

                   =  | -9 + 3 |

 

                   = |-6|

 

                   = 6

 

-3 <--- started at 3 feet below the surface of the water

 

-9 <---- dived down to 9 feet below the surface of the water

 

start at -3 on the number line and count left 6 spaces to -9

 

6 feet
