Accepted Solution

A:
Answer:speed of westbound car= 50 miles/hourspeed of eastbound car = 50 + 4 = 54 miles/hourStep-by-step explanation:Let the speed of westbound car = xAccording to given scenario, speed of eastbound car will be = x + 4NowDistance given = 208 milesTotal time = 2 hoursAs both cars pass each other so by using the formula beloe:Speed of both cars = Distance / Timex + Β (x + 4) = 208 / 22x +4 = 104Subtracting 4 from both sides2x = 104 - 42x = 100Dividing both sides by 2x (speed of westbound car)= 50 miles/hourx + 4 (speed of eastbound car) = 50 + 4 = 54 miles/houri hope it will help you!
