Question

Two RSM students are standing 20ft apart and spot Mrs. Rifkin. If they immediately run opposite directions with speeds of 300 ft/min and 200 ft/min, how many minutes will pass until they are 3,000ft apart?

Answer 1

Answer:

5.96 minutes

Explanation:

Two RSM students are standing 20ft

Speed of one student = 300 ft/min

Speed of other student = 200 ft/m

Time they run till they reach a distance of 3000 ft = x

Distance = Speed × time

$300x+200x+20=3000\\\Rightarrow 500x+20=3000\\\Rightarrow 500x=3000-20\\\Rightarrow 500x=2980\\\Rightarrow x=\frac{2980}{500}\\\Rightarrow x=5.96\ minutes$

∴ Time taken to reach a gap of 3000 ft is 5.96 minutes.
