Answer:
6825
Step-by-step explanation:
From the equation, the series is a geometric series, such that
a = 5
r = 4
n = 6
sum of a geometric series is a(r^n - 1)/(r - 1)
therefore,
sum of the series is 5 x (4^6 - 1) / (4 - 1)
= 5 x (4096 - 1) / 3
= 5 x 4095 / 3
= 6825

Answer:
2:40 PM
Step-by-step explanation:
Terry's 5-minute head start has reduced the distance between them by ...
(5 min)(50 m/min) = 250 m
After Tao starts, at 2:05 PM, the remaining 2350 -250 = 2100 m of distance is being closed at the rate of 50 +10 = 60 m/min. It will take ...
(2100 m)/(60 m/min) = 35 min
to close the remaining distance between the rowers. 35 minutes after Tao starts is 2:05 + 0:35 = 2:40 PM.
