Answer 1

Answer:

Therefore, we get the speed of the man crossing a 600m long street in 5 minutes as 7.2km/h.

Answer 2

Given:

Distance=600m

Time=20 seconds

To find:

The speed of Maggie

Solution:

The speed of Maggie is 108 km/hr. (Option D)

We can find the speed by following the given steps-

We know that the speed of Maggie can be calculated by dividing the distance she has covered by the time taken by her to cover that distance.

Let the speed of Maggie be S.

The speed of Maggie=Distance covered by Maggie/Time taken by Maggie

We are given that the distance covered by Maggie is 600m.

Time taken by Maggie=20 seconds

Using the values,

The speed of Maggie, S=600/20

S=30 m/s

Now, we will convert this speed into km/hr by multiplying the speed by 18/5.

So, speed in km/hr=30×18/5

S=540/5

S=108 km/hr

Therefore, the speed of Maggie is 108 km/hr.
