Question

A girl can run and cross a bridge in 61
seconds. If her speed is 12 km/hour,
find the length of the bridge?​

Answer 1

speed = distance travelled / time taken

changing sppeed in SI unit form

12×1000÷3600 = 3.33 m/s

by formla

3.33 =d / 61

d= 203.13 m

Answer 2

Answer:

speed = distance / time

therefore:

Distance = Speed × time

= 12000 × 61

= 732000 m/s

= 732 km / s

I do not if the answer is correct the u got the formulae so work it out once more
