Question

how to convert 90km/hr in m/sec​

Answer 1

Explanation:

$1km = 1000m$

$1hr = 3600s$

$90 \times 10 00/36 00$

$900/36 \: m/s$

Answer 2

Answer:

90km/hr = (90×1000) /1×60×60

1km =1000m

1hr =60min =60×60 secs

=3600 secs

therefore,

90km/hr = (90×1000) /1×3600

= 90000× 3600

=324 × 10⁶
