Question

A particle travels 16.5 km in 30 minutes. What will be the speed of the particle in km / h ?

Answer 1

s=d/t

Explanation:

s=16.5/0.5

s=33

33 km/h since 30 min is half an hour

Answer 2

`\boxed{ \huge{ \boxed{ \sf{ \bold{33 \: km/h}}}}}`

Explanation:

Distance ( d ) = 16.5 km

Time ( t ) = 30 minutes

( To convert minutes to hour , divide the minutes by 60)

Time ( t ) =
`\sf{ (30)/(60) }` =
`\sf{0.5}` hours

Now, let's find the speed

Speed =
`\sf{ (distance \: travelled \: ( \: in \: km))/(time \: taken \: ( \: in \: hrs)) }`

plug the values

⇒
`\sf{ (16.5)/(0.5) }`

Calculate

⇒
`\sf{33 \: km/h}`

Hope I helped !
