The spider will cross the driveway 25.71 in seconds.
It's a conversion problem, so, in order to solve it, we need to convert the units of the given information. Let's convert the given speed (in cm/s) to m/s.
We know that: 1m=100cm
So, converting we have: 14(cm)/(s)*(1m)/(100cm)=0.14(m)/(s)
Then, calculating the time, we have: distance=speed*time\\\\3.6m=0.14(m)/(s)*time\\\\time=(3.6m)/(0.14(m)/(s))=25.71s
We have that the spider will cross the driveway in 25.71 seconds.
