I’m pretty sure the answer is 7/18
Let the slower cars speed equal X.
The faster cars speed would be X+5 ( 5 mph faster).
They traveled for 3 hours
Multiply the time of travel by speed to equal the number of miles traveled.
So you have:
3X + 3(X+5) = 267 miles
Simplify the left side:
3X + 3X+15 = 267
Combine like terms:
6x + 15 = 267
Subtract 15 from each side"
6x = 252
Divide each side by 6:
x = 252 / 6
X = 42
The slower car was traveling at 42 mph and the faster car was traveling at 47 mph.
Negative times negative = positive.
=0.63−(−9.85)
=0.63+9.85
=10.48
D) is the answer.
3(1,000,000)=3,000,000
3(100,000)=300,000
2(100)=200
3,300,200
