Question

bill is riding his bike he rides 25 miles in 2 hours 37.5 miles in 3 hours and 50 miles in 4 hours find the constant of proportionality proportionality and write an equation to describe the situation

Answer 1

Bill rides a bike with a speed 12.5 mile / hour, because:

25 / 2 = 12.5
37.5 / 3 = 12.5
50 / 4 = 12.5

equation
x - time [hours]
y - distance [miles]

y = 12.5x
