Answer:
Step-by-step explanation:
First we multiply x through (y+1). This equals xy +x.
Second we take 3 through (y+1). This equals 3y+3.
Next we take xy + x through (x+2). This equals 2x squared, y + 2x squared.
Fourth we take 3y+3 through (x+2). This equals 6xy + 6x.
Speed of Sam = Distance / Time
Here, Distance = 1 Km
Time = 1/3 hour
Substitute the values, in the formula:
Speed = 1 / 1/3 = 3 Km/h
Now, In next situation, Speed = 3 Km/h
& Time = 4/5 hour.
Substitute the values, in the same formula:
Distance = Speed × Time
D = 3 * 4/5
D = 12/5 = 2.4 Km
In short, Final answer of your question would be 2.4 Km
Hope this helps!
