Answer 2

What is the speed of a bus if it travels 54km in 90 min?

Answer:  36 km/hr

Step-by-step explanation:

distance travelled=54 km

time taken =90 min

                  ⇒3/2 hours

so speed= distance/time

              ⇒54/3/2

              ⇒54*2/3

             ⇒36 km/hr

now in meter per minute

distance=54km

            ⇒54000m

so speed =distance/time

                ⇒54000/90

                 ⇒600meter /min
