Answer:
<em>Sali's speed was 18.75 km/h.</em>
Step-by-step explanation:
Jane took 3.5 hours to cycle the 63 km.
As,
, so the speed of Jane will be: 
Suppose, the speed of Sali is
km/h
Sali caught up with Jane when they had both cycled 30 km.
So, <u>the time required for Jane to cycle 30 km</u>
and <u>the time required for Sali to cycle 30 km</u> 
Given that, Sali started to cycle 4 minutes or
after Jane started to cycle. So, the equation will be.......

Thus, the speed of Sali was 18.75 km/h.
Answer:
c = 6
Step-by-step explanation:
1/2 (2(4) + 4) = 3(4) - c
1/2 (8 + 4) = 12 - c
1/2 (12) = 12 - c
6 = 12 - c
-6 = -c
c = 6
Answer:
$17,771.92
Step-by-step explanation:
A = P (1 + r/n)^nt
A = Future value (the answer you're trying to find)
P = Initial deposit ($1000)
R = Interest rate (8.25%; this will be represented as a decimal in the equation (.0825))
N = # of times interest is compounded per unit t (12)
T = Time (35)
35 * 12 = 420
1000 (1 + .0825/12)^420
1000(1.006875)^420
1000*17.77191635
A = $17,771.92 (rounded to the nearest hundredths)
