:elaine takes 7 min to ride 18 blocks. what is her unit rate. how long should it take her to go 50

unit rate = 2.57 blocks / min

Time = 19.444 ...

Step-by-step explanation:

The unit rate is how far she can travel in 1 minute.

Rate is defined as distance / time

Givens

distance = 18 blocks

time = 7 minutes

Solution

rate(r) = distance(d) / time(t)

r = 18 blocks / 7 minutes

r = 2.57143 blocks / minute

Set up the ratio for 50 blocks

1 minute / 2.57143 blocks = x / 50 blocks    Multiply both sides by 50

1 * 50 / 2.57143 = x * 50 / 50

x = 50 / 2.57143

x = 19.4444...
