Question

ronny can walk 4 miles in t minutes. at that rate, how long will it take her to walk 11 miles ?

Answer 1

4 miles in t minutes

proportion: miles / time

4/t

For 11 miles:

11/ x

where x is the time it takes to walk 11 miles.

Equal both proportions:

4/t = 11/x

Solve for x:

x = 11 / (4/t)

x = 11 (t/4) = 11t/4

$\frac{11}{4}t$
