At the beginning of my bike ride I feel good, so I can travel 20 miles per hour. Later, I get tired and travel only 12 miles per
Vesnalui [34]

Answer: 3\dfrac{1}{4} hours

Step-by-step explanation:

Let x be the time ( in hours ) you feel good and y be the time ( in hours ) that you get tired.

As per given , we have

x+y= 8

Since : Distance = Speed\times Time

So , we have

20x+12y=122

According to the given question , we have the following system of equations ,

x+y= 8--------(1)\\\\20x+12y=122------------------(2)

Multiply 12 on both sides of equation (1) , we get

12x+12y=96------------(3)

Eliminate equation (3) from (2) , we get

8x=26\\\\\Rightarrow\ x=\dfrac{13}{4}=3\dfrac{1}{4}

Hence, you felt 3\dfrac{1}{4} hours good.

If a train traveled at 50 meters within 120 seconds, what is its speed?
Alja [10]

Answer:

v = 0.416 m/s

Step-by-step explanation:

Give that,

Distance covered by a train, d = 50 m

Time taken, t = 120 s

We need to find the speed of a train. The formula for speed of an object is equal to the total distance covered divided by total time taken. It can be given by :

v=\dfrac{d}{t}\\\\v=\dfrac{50\ m}{120\ s}\\\\v=0.416\ m/s

So, the speed of a train is 0.416 m/s.
