Question

Find the time taken by Suhani to cover a distance of 500 m , if she runs at a

speed of 18 km/hr.​

Answer 1

1Km is 1000 meter

30Km is 30000 meter

so 30000 ➗ 60hours converts it into minutes is 500

and 500 ➗ 60mins converts it into seconds which is 8.3

500meters ➗ 8.3km/sec is 60 Ans

Answer 2

$\tt Speed = 18 km/hr = 5 m/s \\ \tt distance = 500 m \\ \\ \tt we \: know \: that \\ \\ \tt \boxed{\bold{\underline{\green{\tt Speed = \frac{distance}{time} }}}} \\ \\ \tt \therefore time = \frac{distance}{speed} \\ \\ \tt \therefore time = \frac{500}{5} \\ \\ \tt \therefore \boxed{\bold{\underline{\red{\tt Time = 100 \:s }}}}$
