asked • 04/02/20Keyshawn drives 300 miles in twice the time it takes Shelby to drive 240 miles. Shelbys speed is 30 mph greater then Keyshawn’s speed. What is the speed and time of each?

t Keyshawn = 300 / r
t Shelby = 240 / (r + 30)
t Keyshan = 2 t Keyshawn
300 / r = 2 [240 / (r + 30)]
Can you solve for r and answer?
