An object travels 25m.in 7 seconds and another object travels 25 m. in 6 seconds. What is the average speed of the object?
Answers
Answer:
We are given one object that travels 25 m in 4 second at the starting of it's journey and at the end the object travels 15 m in 1 second and we are asked to find the Average Speed of the object.
To calculate the Average Speed of the given object we have to use the given below formula :
\begin{gathered}\ddag\:\: \sf Average \: Speed = \dfrac{Total \: distance \: travelled \: by \: the \: object}{Total \: Time \: taken \: by \: the \: object} \\ \\ \end{gathered}
‡AverageSpeed=
TotalTimetakenbytheobject
Totaldistancetravelledbytheobject
First we need to calculate the total distance travelled by the object and then we have to find the total time taken by the object after finding this two things we can calculate the Average Speed of the object.
\begin{gathered}\bigstar\:\underline{\textbf{ Total distance travelled by the object : }} \\ \end{gathered}
★
Total distance travelled by the object :
\begin{gathered}:\implies\sf Total \: Distance \: travelled = Distance \: travelled \: at \: starting \: of \: the \: journey + Distance \: travelled \: till \: the \: end \: of \: the \: journey \\ \\ \end{gathered}
:⟹TotalDistancetravelled=Distancetravelledatstartingofthejourney+Distancetravelledtilltheendofthejourney
\begin{gathered}:\implies\sf Total \: Distance \: travelled = 25+ 15 \\ \\ \end{gathered}
:⟹TotalDistancetravelled=25+15
\begin{gathered}:\implies \underline{ \boxed{\sf Total \: Distance \: travelled = 40 \: m}} \\ \\ \end{gathered}
:⟹
TotalDistancetravelled=40m
Explanation:
Average speed = total distance traveled by both objects/total time.
a.s = 25+25/7+6
=> 50/13
=>3.8 m/s.(aprox.)
