Question

Mitchell left Detroit on the interstate driving south towards Orlando at a speed of 60 miles per hour. Clark left Detroit 1 hour later traveling at a speed of 75 miles per hour, following the same route as Mitchell. How long will it take Clark to catch Mitchell?

Answer 1

the answer is 4 hours.

Explanation:

x: time clark drove

Y: Mitchells time drove

60 times Y = 75 times x

y=x+1

60(x+1)=75x

60x+60=75x

60=15x (subtract the 60x to the other side)

60/15=4

x=4
