Answer:
5 hours after they start.
Step-by-step explanation:
The distance between the cities Atlanta and Indianapolis is 540 miles.
If a motorcycle's speed is 48 mph, then time taken by motorcycle = Distance / Speed = 540 miles / 48 mph = 11.25 hours.
For a car it takes 2.25 hours less to cover same distance than for the motorcycle. Then time taken by car = 11.25 - 2.25 = 9 hours.
Speed of car = Distance / Time = 540 miles / 9 hours = 60 mph.
If they start moving towards each other simultaneously, then the time when they meet = Distance / (sum of speeds) = 540 miles / (60+48) mph = 540 miles / 108 mph = 5 hours.
Hence, it takes them 5 hours to meet after they start moving towards each other simultaneously.
Answer:
1/5
Step-by-step explanation:
the 5 is the total number of times he tried
the 1 is how many times he rolled a 1
The current area is 15 x 9 = 135 square feet.
He wants to increase both the length and width by X:
Set up an equation:
(15 +x) * (9 +x) = 135 * 2
Simplify :
x^2 + 24x + 135 = 270
Subtract 270 from both sides:
x^2 + 24x - 135 = 0
Use the quadratic formula to solve for x:
-24 +/- √(24^2 - 4(1*-135) / 2*1
x = 4.7 or -28.7
The answer has to be a positive value, so x = 4.7 feet.
-4 is the answer. 10-6 is 4. 4-8 is -4
