4. 35 miles per 1 hour
5. $7 per 1 hour
Step-by-step explanation:
A unit rate is the rate of measurement of an object per 1. Its feet per 1 hour or dollars per 1 item or 1 ounce. To find the unit rate divide the two measurements to a simpler fraction with 1 as the denominator or divide to a decimal if necessary.
Examples:

Answer:
4 tiles
Step-by-step explanation:
Area of a square tile:
A = s²
A = (30)²
A = 900 cm
900 cm = 9 m
Area of the square room:
A = s²
A = (6)²
A = 36 m
36 ÷ 9 = 4
45 minutes = 3/4 hours
so his speed = 6 / 3/4 kph
= 8 km / h Answer
