Scale factor helps you properly scale down a figure so that way they would be similar, therefore ‘similar figures’ and then the sides of the figures would be proportional

On a particular day, the wind added 5 miles per hour to Alfonso's rate when he was cycling with the wind and subtracted 5 miles
sattari [20]

speed with no wind = s

speed with wind = s + 5

speed against wind = s - 5

time = t

speed = distance/time

distance = speed * time

With wind, time = t, speed = s + 5, distance = 50

50 = (s + 5)t

Against wind, time = t, speed = s - 5, distance = 30

30 = (s - 5)t

t = 30/(s - 5)

50 = (s + 5) * 30/(s - 5)

50(s - 5) = (s + 5) * 30

50s - 250 = 30s + 150

20s = 400

s = 20

Answer: 20 mph
