Answer:
400
Step-by-step explanation:
u = 50 km/hr
v = 100 km/hr
d = 300 km
b = 200 km/hr
= b*d/(u+v)
= 200* 300/(50+100)
= 400

Answer:
0.2332
Step-by-step explanation:
The relationship between the effective annual yield (e) and the nominal annual interest rate (r) compounded n times per year is ...
e = (1 +r/n)^n -1
For weekly compounding, we have n=52, so ...
e = (1 +0.21/52)^52 -1 = 0.2332 . . . . . . . about 23.32%
