Answer:
33 feet below surface
Step-by-step explanation:
A scuba diver is 15.5 feet below the surface of the water. If the diver continues to swim downward at a rate of 2.5 feet per second, what is her location, in feet, relative to the surface after 7 seconds?
time swimming × swimming rate
= 7 × 2.5
= 17.5 feet in 7 seconds
The diver begins at 15.5' below surface so depth after 7 seconds:
15.5 + 17.5 = 33 feet below surface
