Question

A peraon walks distance of 30 m towards west with speed of 2m/s and 40 m towards north with speed of 1.5m/s . Then average speed​

Answer 1

Answer:

speed equals to 1.5+2/2=1.75

Explanation:

1.75 is the right answer

but i not sure about my answer

Answer 2

Answer:

Explanation:

➡️Total time taken is -

t = s1/v1 + s2/v2

t = 30/2 + 40/1.5

t = 15 + 23.33

t = 38.33 s

➡️Total distance travelled is given by

d = s1 + s2

d = 30 + 40

d = 70 m

➡️Displacement is given by-

s = √(s1^2 + s2^2)

s = √(30^2 + 40^2)

s = 50 m

➡️Average speed is calculated by-

➡️vavg = d / t

➡️vavg = 70 / 38.33

➡️vavg = 1.826 m/s

➡️Average velocity is calculated by-

v = s / t

v = 50 / 38.33

v = 1.304 m/s...
