Question

Netra and Nimrah have to cover different distances to reach their school but the take the same time to reach the school. What can you say about their speed?

Answer 1

as they both are taking same time and we know the formula that
speed=distance/time

so we can say the one who is farther from school have higher velocity as compared to the one who is nearer to school

Answer 2

Since both Netra and Nimrah cover different distances taking same amount of time it means either Netra’s speed is greater than or less then Nimrah’s speed.

Mathematically,

Let D1 be the distance covered by Netra and D2 be the distance covered by Nimrah respectively.

Let T1 be the time taken by Netra and T2 be the time taken by Nimrah respectively.

According to the question,

T1 = T2 = T.

Now, as we know that

Speed = Distance/Time

Let, S1 be the speed of Netra

Therefore, S1 = D1/T     ----------- equation 1

Similarly S2 = D2/T      ------------- equation 2

From equation 1 and 2 we get,

D1/S1 = D2/S2

=> S2/S1 = D2/D1

Thus it implies that ratio of their speeds is equal to the ratio of their distances.
