Answer 1

Answer:

(a)25 m/s

(b)33/12 m/s

Explanation:

to convert km/h to m/s we have to multiply with 5/18 and,

to convert m/s to km/h we have to multiply with 18/5

so(a) 90km/h= 90×5/18 m/s

= 25 m/s

(b) 165m/min

here its given min that means:

in 60sec (1min) it travells 165m

so in 1 sec it will travel 165/60 = 33/12 m
