Solution (8):
Note that:
Finding out how much miles in 1 minute:
- 0.5 miles = 8.5 minutes
- => 0.5/8.5 = 1 minute
- => 1/17 miles = 1 minute
Hence, the unit rate in miles per minute is 1/17 miles per minute.
Solution (9):
Note that:
- 7/8 square yards = 1/20 hours
Finding, how much yards in 1 hour:
- 7/8 square yards = 1/20 hours
- => 7/8 x 20 square yards = 1/20 x 20 hour
- => 7/2 x 5 square yards = 1 hour
- => 35/2 yards² = 17.5 yards² = 1 hour
Hence, the unit rate in square yards per hour is 17.5 square yards per hour.
