Question

Convert a speed of A,54 km per hour B,90 km per hour.

Answer 1

Answer:

15 m/s & 25 m/s

Explanation:

A = 54 kmph

= 54 × km / (hr)

= 54 × 10³ m / (3600 s)

= [54 × 5/18] m/s

= 15 m/s

B = 90 kmph

= 90 × km / (hr)

= 90 × 10³ m / (3600 s)

= [90 × 5/18] m/s

= 25 m/s

Answer 2

15 m/s & 25 m/s

Explanation:

A = 54 kmph

= 54 × km / (hr)

= 54 × 10³ m / (3600 s)

= [54 × 5/18] m/s

= 15 m/s

B = 90 kmph

= 90 × km / (hr)

= 90 × 10³ m / (3600 s)

= [90 × 5/18] m/s
