Answer: The Answers are A, and C.
3 multiplied by 20 is 60
Multiply this by 10 and you get 600
1 Multiplied by 30 is 30
Find the total of the two answers (Which is 630) this is your answers
Let x be the speed of the first car in miles per hour. After 12 hours it will have gone 12x miles. The other car, driving east, has speed x+ 4. After 12 hours it will have gone 12(x+ 4) miles. Again by the Pythagorean theorem,
(12x)^2+(12(x+4)^2=600^2. Solve that equation for x.
