7. Tina rides her electric bicycle 10 km/h faster than Tony. Tina can travel 60 km in the same time that is takes Tony to travel 40 km. Determine Tina's average speed and Tony's average speed.
State the variable used and what it represents. Show all WORK.

answer: it actually depends on which is the independent variable and which is the dependent variable. let us say we're looking at a linear equation. y=2x+3. we theoretically could switch the equation to be x=(y-3)/2 and it would be the same line. so either a causes b or it can be that b causes a. so technically the answer is false

step-by-step explanation:

2+2 obliviously is 4.
