Question

The distance travelled by an auto rickshaw in 12 minutes is 5 km find out the speed of the auto rickshaw in km/hr and m/s

Answer 1

Answer:time =12min=12/60hr=0.2hrs

distance=5km

speed=distance/time

speed=5km/0.2hrs

speed=25km/hr

now ,the speed in m/cm is 25x18/5=90m/s

Explanation:

Answer 2

Given:

Distance traveled by auto-rickshaw = 5 Km

Time is taken by auto-rickshaw = 12 minutes

To find:

Speed of auto-rickshaw in Km/h =?

Speed of auto-rickshaw in m/s =?

Stepwise Solution:

• The speed can be calculated in the following steps:

• Step 1: Converting the units of time and distance as per units of speed

• The time is given in minutes therefore it should be converted into an hour and seconds.

• Time in hour:

        Time = 1 hour = 60 minutes

        Time (h) = t (h) = 12 minutes

        Time (h) = 12 ÷ 60

        Time (h) = 1/5 hour

• Time in seconds:

         Time = 1 minute = 60 seconds

         Time = 12 minute = t (s)

         Time = 12 × 60

         Time = 720 seconds

• The distance is given in kilometers and it should also be converted into meters.

• Distance in meter:

       Distance = 1 Km = 1000 meters

       Distance = 5 Km = D (m)

       Distance = 5 × 1000

       Distance = 5000 meters

• Step 2: Calculate the speed using the given formula

• Speed in Km/h:

      Speed (Km/h)= Distance(Km) / Time(h)

       Speed (Km/h)= 5 Km / 1/5 h

       Speed = 25 Km/h

• Speed in m/s:

      Speed (m/s)= Distance (m)/Time(s)

       Speed (m/s) = 5000 m/720 s

       Speed = 6.94 m/s

Hence, the speed of an autorickshaw in Km/h is 25Km/h and its speed in m/s is 6.94 m/s.
