Question

. Calculate the speed of a vehicle covering 180km in 2hr. Express in km/h and m/s

Answer 1

Answer:

90km/h

Explanation:

25m/s hoga =90×18/5

Answer 2

distance =180km

time=2h

we know that,

speed=distance÷ time

speed=180÷2

speed=90km/h

speed of vehicle in km/h =90km/h

to find speed of vehicle in m/s,

first we have to express 90km/h into m/s

distance=90km =》90×1000 =》90,000m

time= 1h =》60 minutes =》60×60 =》3,600 s

speed = distance÷time

=90,000÷3,600

=25m/s
