Beth drives 13 miles faster than Marcus. After 4 hours they are 452 miles apart. Find their rates. Let b = B's driving rate Let m = M's driving rate : Write a distance equation: dist = time * rate : M's dist + B's dist = 452 4m + 4b = 452 : It says,"Beth drives 13 miles faster than Marcus."; the equation for this is: b = (m+13) : Replace b with (m+13) in the 1st equation 4m + 4(m+13) = 452 4m + 4m + 52 = 452 8m = 452 - 52 8m = 400 m = m = 50 mph, then b = 50 + 13 b = 63 mph : : See if that's true 4(50) + 4(63) = 452
