A = 54 + 5t
A = 84 + 2t
54 + 5t = 84 + 2t
5t - 2t = 84 - 54
3t = 30
t = 30/3
t = 10....they will reach the same investment in 10 years
Solution:
3:36 PM.
The clock loses 10 minutes each hour,
so it loses 5 minutes every half-hour,
and it loses 1 minute very 6 minutes.
It is 12:50 PM at 1:00 o'clock.
It is 1:40 PM at 2:00 o'clock.
It is 2:30 PM at 3:00 o'clock.
It is 2:55 PM at 3:30 o'clock.
It is 3:00 PM at 3:36 o'clock.
