Answer:
5002
Step-by-step explanation:
The given series is an arithmetic progression with
a = the first term
d = common difference
n = number of terms
S = the sum of the nth term
Recall that
S = n/2(2a + (n-1)d)
As such,
a = 2
d = 8 -2 = 14 - 8 = 6
n = 41
Hence
S = 41/2(2*2 + (41 - 1)6)
= 41/2 ( 4+ 240)
= 41 * 244/2
= 5002

Answer:
about 24.58 m/s
Step-by-step explanation:
Multiply by conversion factors that change the units, but not the value.
(55 mi/h) × (1609 m/mi) × (1 h)/(3600 s) = (55×1609/3600) m/s
= 88495/3600 m/s ≈ 24.58 m/s
_____
<em>Additional comment</em>
The exact conversion uses 1609.344 meters per mile, so gives exactly 24.5872 m/s.
Answer:
The above has one solution
