d = 5,000 mi the distance between the missiles
v1 = 2,000 mph the rate of the first missile
v2 = 1,000 mph the rate of the second missile
t = 1 min = 1/60 hr
Since distance = speed*time the distance 1 minute before the impact is:
v1t + v2t = t(v1 + v2) = (1/60)(2,000 + 1,000) = 50 miles.
Answer:
<em>Multiply by 100</em>
Step-by-step explanation:
The equation is given as:
-m + 0.02 + 2.1m = -1.45 - 4.81m
To eliminate the decimals from all the terms, we must multiply by a number that make all the coefficients integers.
The decimal coefficients and independent terms are
0.02, 2.1, 1.45, 4.81
Note the maximum number of decimals found in all of them is 2. Thus, multiplying by 100 all the decimals will vanish as follows:
100(-m + 0.02 + 2.1m) = 100(-1.45 - 4.81m)
-100m + 2 + 210m = -145 - 481m
Now all terms have integer coefficients as required.
