Distance Firework B would have traveled after 0.25 seconds:
240 x 0.25 = 60 feet
Let x be the time that it will explode together:
60 + 240x = 340x
100x = 60
x = 60 ÷ 100
x = 0.6 sec
Firework A will explode at 0.6 seconds after it is launched
Firework B will explode at (0.6 + 0.25) 0.85 seconds after it is launched.
-------------------------------------------------------------------------------------------------
Answer: Firework B will explode at 0.85 seconds after it is launched.

4 more students can go for $240
240/60= 4
So when you subtract by a negative number, it is the same thing as adding the two numbers.
First find a the LCD, or the least common denominator.
LCM(7,6) = 7•6 = 42
Then make the fractions have 42 as a denominator.
7 5/6 • 7/7 = 7 35/42
4 1/7 • 6/6 = 4 6/42
Finally, add the two mixed numbers
7 35/42
+4 6/42
11 41/42
So 11 41/42 is your answer
It should just be 3 15/16 because you can’t really simplify 15/16 because it’ll just give you decimals. For example; 15/3 is 5 but 16/3 is 5.333.... and 15/5 is 3 and 16/5 is 3.2, and 15/2 is 7.5 and that won’t work because it turns into a decimal.
