Question

A vehicle running with the speed of 90km/hr.,The speed of the vehicle in meter second would be​

Answer 1

Explanation:

$speed \: = 90 \frac{km}{h} \\ \\ = 90 \times \frac{1000 \: m}{60 \times 60 \: sec} \\ \\ = 30 \times \frac{5}{6} \\ \\ 25 \: \: \: \frac{m}{s}$

Answer 2

speed = 90 km/hr

1 km = 1000m

1 hr = 60 × 60 = 3600 secs

Speed = 90 × 1000 m/ 3600 sec

Speed = 900 / 36

Speed = 25 m/s

Therefore, 90 km/hr = 25m/s
