Lupe can ride her bike at a rate of 20 mph when there is no wind. On one particular day, she rode 2 miles against the wind and n

lana [24]

Let wind speed = x mph

when she rode 2 miles against the wind we have:-
speed = distance / time so
20 - x = 2 / t -------(1) where t is the time she took.

when riding with the wind we have

20 + x = 3 / t--------(2) adding equations (1) and (2):-

40 = 2/t + 3/t
40 = 5/t
t = 5/40 = 1/8 hr

x = 20 - 2 / 1/8 = 20 - 16 = 4

Wind speed was 4 mph Answer

Answer:

$6 \frac{1}{14}$

Step-by-step explanation:

Write down the problem;

$2 \frac{4}{7} + 3 \frac{2}{4}$

Simplify

$2 \frac{4}{7} + 3 \frac{1}{2}$

Convert so that the fractions have a common denominator; multiply the numerator and denominator of both fractions such that the denominators are equal;

$2 \frac{8}{14} + 3 \frac{7}{14}$
