A woman driving a car 14 ft long is passing a truck 30 ft long. The truck is traveling at 50 mi/h. How fast must the woman drive her car so that she can pass the truck completely in 6s?

• Algebra -

(30 + 14)/6 = speed

Convert from feet per second to mph.

I hope this helps.

• Algebra -

let the speed of car =xmi/h
relative speed =(x-50)mi/h
time taken to overtake=1/600h
s=d/t
distance to be covered=44/5280mi
s*t=d
(x-50)(1/600)=44/5280
x=55mi/h
