Answer:

20 seconds

Step-by-step explanation:

A is moving at the speed of 6t and B is moving at the speed of 5t. 6t +5t = 11t, and 220 divided by 11 = 20.

KonstantinChe [14]

Answer:

6.5 %  

Step-by-step explanation:

The simple interest formula is

I = Prt

Data:

I = $1755

P = $3000

t = 9 yr

Calculation:

1755 = 3000 × r × 9

1755 = 27 000 r

Divide each side by 27 000

r = 1755/27 000 = 0.065 = 6.5 % APR

The annual percentage rate was 6.5 %.
