Answer:
30 hours
Step-by-step explanation:
The relation between time, speed, and distance is ...
time = distance/speed
time = (15 km)/(0.5 km/h) = 30 h
It takes 30 hours for the lava to reach the sea.
If x be one angle then its complementary angle = 90-x
therefore we can write the equation:-
x - (90- x) = 84.8
2x -90 = 84.8
2x = 174.8
x = 174.8 / 2 = 87.4 degrees
and its complement = 90 - 87.4 = 2.6 degrees
<span>Let Ah be Annie's hour of travel in 1 day and Bh be
Brian's hour
to get Brian's hour of travel:
Ah + Bh = 20
5 (Bh +2 ) + Bh= 20
5 Bh + 10 + Bh=20
6 Bh = 20 - 10
<u>6Bh</u> = <u>10</u>
6 6</span>
Bh =1.66
To get Ah of travel 1 day
Ah = 5 (Bh + 2)
<span> = 5 (1.66 +
2) </span>
<span>
= 5 ( 3.66 )</span>
Ah = 18.30
Checking:
Ah + Bh =20
<span>
18.30 + 1.66 = 20
</span><span>19.96 = 20</span>
<span>
20 = 20</span>
(19.96 is rounded off)
