Answer:

1km/h =5/18m/s

Step-by-step explanation:

we need to find time here

we know that time=distance /speed

speed=80*5/18

distance=500

time=

 \frac{500}{ \frac{5}{18} \times 80 }

 \frac{500 \times 18}{80 \times 5}

 \frac{50 \times 18}{8 \times 5}

 \frac{10 \times 18}{8\times 1}

 \frac{5 \times 9}{2}

 \frac{45}{2}
