Question

calculate speed in m/s when distance=0.45km, Time=15minutes​

Answer 1

Distance =0.45km

D=0.45×1000

D=450m

Time=15min

T=15×60

T=900s

S=D/T

S=450/900

S=0.5m/s

Answer 2

Dear friend,

Distance = 0.45 km = 0.45 × 1000 m = 450 m

Time = 15 minute = 15 × 60 s = 900 s

Speed = Distance ÷ Time

= 450 ÷ 900 m/s

= 45 ÷ 90 m/s

= 5 ÷ 10 m/s

= 0.5 m/s

Answer: Speed is 0.5 m/s.

Hope it helps !!!
