Answer:
Step-by-step explanation:
Let x be the speed in heavy traffic and y be the speed in light traffic in miles per hour.
Total distance = 95 miles
Time taken in heavy traffic = 50 minutes = hour
We know that
Distance traveled in heavy traffic =
Time taken in light traffic = 1 hour
Distance traveled in light traffic =
Since, Total distance = 95 miles
Also, Her speed in heavy traffic 40 miles per hour slower than her speed in light traffic.
Multiply this equation by 5 on both sides, we get
Add (3) and (1), we get (5x will be cancelled)
From equation, (2), we get
Hence, Her speed in heavy traffic is 30 miles per hour and in light traffic is 30 miles per hour.
