Answer:
1.2 hours
Step-by-step explanation:
Recall :
Distance = speed * time
Let the time taken = x
Creating an equation for the question :
Distance of train A + Distance of train B = 192
70 * x + 90 * x = 192
70x + 90x = 192
160x = 192
x = 192 / 160
x = 1.2
It takes 1.2 hours to be 192 miles apart.
10. Your multiplying the 4 to the "x" which makes 4x then you multiple the 4 to the 3 and get 12. So the answer would be 4x+12. Basically the 4 is the property and your distributing the parentheses. a property is any characteristic that applies to a given set.
200,000+10,000+8,000+300+70+5 is 218,375 in expanded form!!!
