If one is at a speed of 35 mph and the other 60, sum the speeds to work with just one number:
35 + 60 = 95mph
The formula for time is:
Time = Distance / Speed
Time = 855 / 95
Time = 9h (D.)

Answer:
220 cents, $2.20
Step-by-step explanation:
Count the amount of QUARTERS there are.
7 quarters.
The next coin in the photo is a dime.
4 dimes.
The next coin in the photo is a penny.
5 pennies.
Quarters are worth 25 cents, dimes are worth 10 cents, and pennies are worth 1 cent.
25(7) + 4(10) + 5(1) = v (the total value)
25 * 7 = 175 cents
4 * 10 = 40 cents
5 * 1 = 5 cents
175 + 40 + 5 = v
175 + 40 = 215 cents
215 + 5 = 220 cents
The value of all of those coins is 220 cents, or $2.20.
Answer:
Angle BCA = 90

Where the angle opposite of the hypotenuse ( or diameter ) is the right angle
Angle BCA is the angle opposite of the diameter
Hence BCA = 90
