please mark me as the brainliest

Step-by-step explanation:

speed = distance / time

speed = 20 m/s

time = 3 hrs = 3 × 3600 = 10800 seconds

distance = speed × time

= 20 × 10800

distance = 216000 metres

Answer 2

Answer:

distance is iven as the product of speed and time taken

speed = 20 m/s

time = 3 hr

       = 3 × 60 × 60

       = 10800 sec

distance = 20 × 10800

               = 216,000‬ m

               = 216 km

Hence the distance travelled will be 216 km
