Question

An electric engine has a velocity of 60 km/h.How much distance will it travel in 18 s? A.360 m B.300 m C.400 m

Answer 1

Answer:

300m (B)

Explanation:

First, convert time given in seconds to hours.

Then we get, 18 s = (18 /60 x 60)hrs.

distance = velocity x time

              = 18/(60 x 60) x 60 km

              = 18/60 km

              = (18/60 x 1000) m

              = 300 m (Ans)

Answer 2

Answer:

300 m

Explanation:

velocity = displacement / time

∴displacement = velocity × time

                         =(60×1000/60×60) × 18

                          =300 m
