Question

in race a girl runs 200 meter in 40 second her average speed is . a. 5 m/s b. 10 m/s. c . 15m /s d. 20 m /s.​z​

Answer 1

Solution:-

Girl run 200 meters in 40 sec.

Total Distance = 200 m

Total time taken = 40 sec

$\bf \: average \: speed = \frac{total \: distance}{total \: time \: taken}$

By applying the formula we get

$\bf \: average \: speed \: = \frac{200m}{40s}$

$\bf \: average \: speed \: = \: 5m {s}^{ - 1}$

Answer = 5m/s , option a is correct

$\bf \large{ \underline{ \underline{ \red{answer : }}}}$

Given:-

• Total distance = 200 m
• Total time taken = 40 s

$\large \boxed{ \tt{average \: \: speed \: \: = \frac{total \: \: distance}{total \: \: time \: \: taken}}}$

using in Formula...

$\bf \red { average \: \: speed = \frac{200 \: m}{40 \: s \: \: = 5 }{ms}^{ - 1} }$

Correct answer ☑️ is option (a)
