Answer:

126 minutes or 2 hours and 6 minutes

Step-by-step explanation:

Find how long it took her to swim one lap

1 hour and 30 minutes = 90 minutes

90/5 = 18

This means it took her 18 mins to swim each lap

18 · 7 = 126

It took her 126 minutes/2 hours and 6 minutes to swim 7 laps

A. you plug in to a calculator, which will give 1840.986 so you need to round up to 1840.99. if you truncate it to .98 then he won't reach 2000 in 3 years

b. for this one if you look at the equation given to find the principle it is principle = result (1+rate) ^ -time

if you re arrange this you get result=principle (1+rate)^time
so result = 1840.99(1.028)^5
= 2113.57
