Answer:

  • 5 hours

Step-by-step explanation:

The cars travel in opposite directions from the same point.

Each hour they travel:

  • 50 + 35 = 85 miles

After x hours they will be 425 miles apart:

  • 85x = 425
  • x = 425/85
  • x = 5

combined speed

  • 35+50=85mph

Time be t

Speed=Distance/Time

  • Time=Distance/Speed
  • Time=425/85
  • Time=5h
