Question

student a.travels a distance 75 in 15 sec and student 13 travels a distance of 80 m in 20 sec whose speed is more​

Answer 1

Given :-

Distance travelled by student A = 75 m

Time taken by student A = 15 sec

Distance covered by students B = 80 m

Time taken by student B = 20 sec

To Find :-

Compare the speed of both the students, mention who is greater.

Analysis :-

Here we are given with the distance and time of two students A and B respectively.

Using the formula of speed substitute the given values from the question and compare accordingly.

Solution :-

We know that,

d = Distance

t = Time

s = Speed

Speed covered by student A,

Using the formula,

Speed = Distance/Time

Given that,

Distance (d) = 75 m

Time (t) = 15 sec

Substituting their values,

⇒ s = d/t

⇒ s = 75/15

⇒ s = 5 m/s

Speed covered by student B,

Using the formula,

Speed = Distance/Time

Given that,

Distance (d) = 80 m

Time (t) = 20 sec

Substituting their values,

⇒ s = d/t

⇒ s = 80/20

⇒ s = 4 m/s

By comparing both,

5 > 4

Student A > Students B

Therefore, the speed of students A is higher.
