Answer :
Answer:
48.5 and 60.5 mph
Step-by-step explanation:
Given distance between A and B is 364 miles
Let they meet after y and 364 - y miles.
And, Let speed of one car is x then speed of other car will be (x + 12) mph
Also time after they meet is 3 hours and 15 minutes = 13 ÷ 4 hours.
Using the distance- time formula,
We get equation:
[tex]\frac{13}{4}=\frac{364-y}{x+15} \\and, \frac{13}{4}=\frac{y}{x}[/tex]
Thus, After simplifying we get,
13x + 4y = 1261
and, 13x - 4y = 0
Solving we get the value of x = 48.5
Thus, the Speed is 48.5 and 60.5 mph
