Problema Solution
A sink is being filled with water. After 15 seconds the sink is 1/4 full. How much longer will it take to fill the sink if the water rate is constant?
Answer provided by our tutors
the rate is 1/4 sink in 15 seconds or v = (1/4)/15 sink per second
v = 1/60 sinks per second
t = the time needed to fill one sink
1 since / t = v
1/t = 1/60
t = 60 seconds
it takes 60 second to fill the sink.
60 - 15 = 45 second
after 45 seconds the sink will be full.
