s2008m [1.1K]

Answer:

63.1 seconds.

In this case, since the average adult heart pumps 84.0 mL/s of blood, it means 84.0 mL each second, as we have 5300. mL, the following mathematical set up help us to compute the required time:

t=5300.mL*\frac{1s}{84.mL}\\\\t=63.1s

Which is about 1.05 min.

Best regards!
