Question

Rahul completes 500 race in 30 second. Calculate its speed in km/hr unit​

Answer 1

Answer:

Rahul's speed in km/hr is 60 km/hr .

Explanation:

Distance covered by Rahul =500 m=500/1000 km=0.5 km

Time taken by Rahul = 30 s = 30/3600 h = 1/120 hr

$speed = \frac{distance}{time} \\ = \frac{0.5 \: km}{ \frac{1}{120 } hr} \\ = 0.5 \times 120 \frac{km}{hr} \\ = 60 \: \frac{km}{hr}$

Speed of Rahul is 60 km/hr .
