Question

An objects moves 360km in 2 hours. Calculate its speed in km/h and m/s. (2m)

Answer 1

Answer:

180km/h,

Explanation:

find yourself

Answer 2

Answer:

The speed in km/hr is 180 km/hr

The speed in m/s is 50 m/s

Explanation:

Distance = 360 km

Time = 2 hrs

ATQ,

First we calculate the speed in km/hr

Now ,

speed = distance / time

S = 360 / 2

S = 180 km/hr

Now , we calculate the speed in m/s

To calculate the speed in m/s , we have to

convert the km into m and hr to sec.

so,

converting km to m :

360 km = 360 × 1000m

= 360000 m

converting hr to sec

2hr = 2 × 3600 sec

= 7200 sec

Now, putting the value of distance and time

we find the value in m/s

speed = distance / time

S = 360000 / 7200

S = 50 m/s
