Answer 2

Answer:

Find :- speed in metre per sec

Given :- Distance = 54 km

Time = 90 min

Solution :-

=> Convert 54 km into metre

we know that, 1 km = 1000 m

so, 54 km = 54*1000

= 54000 metre

=>Convert the minutes to second

So, 90 minutes = 5400 seconds

=>Speed = Distance /time

Speed = 54000/5400

Speed = 10 m/sec

Hence, speed is 10 m per second ✔️

"Additional information"

1) Speed = Distance / time

2) Time = Distance / speed

3) Distance = Speed * time
