Answer:
120 miles
Step-by-step explanation:
Distance = 150 miles
train 1 = 60 mph
train 2 = 90 mph
directions of trains = towards each other
Time to meet = 150/(60+90) = 150 miles / 150 mph = 1 hour
Speed of fly = 120 mph
Since fly has been flying for one hour, it travelled 120 miles.
Answer:
7
Step-by-step explanation:
7 hair bows for 21 dollars
One metre=10 decimetres.
Therefore 30 metres = 30*10=300 decimetres.
Given that total amount of metal in the beginning = 8.2 square feet
Given that used amount of metal = 2.1 square feet
Then remaining amount of metal = (8.2-2.1) = 6.1 square feet
Now it says that "$183 worth of sheet metal remaining".
That means cost of 6.1 square feet is $183.
Let cost of 1 square feet of the metal = x
Then cost of 6.1 square feet of the metal = 6.1x
Both expressions 6.1x and $183 represent the cost of the remaining metal so the required equation will be:
6.1x=183
Now we can solve it to find the solution
x=183/6.1
x=30
So the cost per square feet of the metal = $30
Hence final answer is $30 per square feet.
The answer would be C. This is because of Pythagorean theorem. A^2 + B^2=C^2
