Answer 1

Given

Distance = 30 km

Time = 1 1/2 hours = 3/2 hours

Find

rate in km per hour

Step-by-step explanation

we need to find the rate in km per hour.

as we now the rate is also called a speed

so , speed = distance/time

`\begin{gathered} rate=(distance)/(time) \\ \\ rate=(30)/((3)/(2)) \\ \\ rate=(30*2)/(3) \\ \\ rate=(20km)/(h) \end{gathered}`

Final Answer

Therefore, the rate of ship is 20km/hr

so , the correct option is 1.
