Question

A student has to reach his school in 15 minutes . If the school is 800 metres away , at what speed should he walk ?

Answer 1

speed = distance /time

s= 800/ 15 x 60

s= 1m/s

Answer 2

Answer: 8/9 m/sec (or) 0.889 m/sec

Step-by-step explanation:

Distance = 800 m

Time = 15 mins = 15*60 sec

Speed = Distance/Time

           = 800/(15*60)

           = 80/90

           = 8/9 m/s (or) 0.889 m/s
