Question

math a scientist uses a submarine to study ocean life she begins at sea keve which is and elevation of 0 ft she travels straight down for 80 seconds at my a speed of 4.0 ft per second she travles directly up for 20 seconds at a speed if 3.4 ft per second write an integer that represent a the submarines location after 100 seconds period plz answer before 8pm

Answer 1

Use the formula rate x time = distance


(rate going down)(time going down) = distance going down
(4.0 ft/s)(80 s) = 320 ft

Similarly,
(3.4 ft/s)(20 s) = 68 ft

distance traveled downward + distance traveled upward = total distance or location

320 feet + 68 ft = 388 feet below sea level
