Farah and Athena were attempting to push Kieran on the scooter with enough force so that Kieran would run into Mr. Collins. They figured out they needed a 75 N force to run the scooter into Mr. Collins.
Farah and Athena were both applying force from the left, Farah applying a 30 N force and Athena
pushing with a force of 25 N. Were they able to get Kieran to run into Mr. Collins? How can they get it to
hit him?

The independent variable would be the fertilizer as it is what the dependent variable (the growth of grass) depends on.

The answer is -6hope this

Distance covered = speed x timethe distance traveled going against the stream = distance traveled with the stream.therefore it is the speed and the time that are the variables.as he travels the same distance both ways, speed x time is the same for each way.going upstream his speed is 4 kph; going downstream his speed is 6 kph.therefore we have two simultaneous equations: time upstream x 4 = time downstream x 6time upstream + time downstream = 60 minutestherefore we have the equation: time upstream = 6/10 hour, time downstream therefore = 4/10 hour.distance traveled at 4km/hr in 6/10 hour = 24/10 = 2.4km.check: distance traveled at 6km/hr in 4/10 hour = 24/10 = 2.4km.
