Answer 2

Concept :

A measure of how slowly or quickly an object moves. A distance is calculated by dividing the distance travelled by the time required to travel it. Distance + Speed = Time, as speed increases, time will decrease and vice versa.

Given: A takes$3 min 45 seconds$ to complete a kilometer. B takes $4 minutes$to complete the

same $1 km$ track if A and B were to participate in a race of $2 kms$.

Find: We have to B in terms of distance.

Solution:

A takes $3 min 45 sec$ to run a kilometer, while $8 takes 4 minutes$. That is, B takes 15 more seconds to complete a kilometer. So, A will win the race by$2×15=30 sec.$

To measure the distance by which A will win, we need to find the distance that B will run in $30 seconds.$

We know that B takes 4 minutes to run a km. so his speed is $10004$

= $250 m/min = 25060 m/sec$

Therefore, in $30 seconds$ B will run a distance of

= $125 meter;$

Hence B in $125 meter;$
