Answer 1

A - She can ride 43.2 miles in 2 hours.
B - It would take her about 11.1 minutes.

C - She can ride 21.6 miles in 1 hour. (IF THEY WANT IT IN MILES PER MINUTE: She can ride 0.36 miles in 1 minute.)

Explanation:

Set up proportions for each :

A - 18/50 = x/120

120(8) = 50x

2160 = 50x

x = 43.2 minutes

B - 18/50 = 4/x

18x = 50(4)

18x = 200

x = 11.1 (repeating)

C - 18/50 = x/60 minutes

18(60) = 50x

1080 = 50x

x = 21.6
