Question

solve when d=100m t=2min v=?​

Answer 1

Answer:

speed (v)=distance/time

so,v=100m/120sec

=0.83333333....

Answer 2

Given:

• Distance covered is 100m.
• Time taken is 2min

To Find:

• The speed from the given data .

Concept Used:

• We will use the formula which us stated as Speed × Time = Distance.

Note: This formula is only valid for non accelerated motion.

Solution:

We are here given that an object covers 100m with a speed of v in time t .

Using the formula mentioned;

$\sf{\implies s=v\times t}$

$\sf{\implies 100m = v \times 2min }$

$\sf{\implies 100m =v\times 2\times 60s}$

$\sf{\implies 100m =v\times 120s}$

$\sf{\implies v=\dfrac{100m}{120s}}$

$\sf{\implies v=\dfrac{5}{6}ms^{-1}}$

$\red{\sf{\leadsto v=0.83m/s(approx)}}$

Therefore speed is 0.83m/s. (approx)
