Given that the ship was traveling for 4 mph faster heading west than south then let the speed of the ship heading south be x mph, the speed of the ship heading west will be (x+4) mph
the distance is given by:
distance=speed*time
distance heading south was:
x*4=4x miles
distance heading west was:
5(x+4)=5x+20
thus the total distance will be given by:
4x+(5x+20)=191
9x+20=191
9x=191-20
9x=171
x=171/9
x=19 mph
the speed the ship used to travel west was:
x+4
=19+4
=21 mph
Answer:
no to boring
Step-by-step explanation:
Answer:
=11600/3
=3866.66kg
Step-by-step explanation:
dividing the mass with bricks with the three times of the lorry
1kg = 2.205lbs
10mg per 2.205
10/2.205
10 mg/2.205lbs = x/88lbs
Now we solve for z
10 times 88 = 880 divided by 2.205 =
(Nearest tenths) = 399.1
Thats for the day, there are 2 doses in one day, divide it by 2.
Which equals to 199.55
Answer: 199.55mg
