701 = 21 + 68w
701-21= 680
680/68=10
w=10
The unit rate would be number of miles per hour ( 1 hour).
Divide the total number of miles by the total number of hours:
100 miles / 4 hours = 25 miles per hour.
The unit rate is 25 miles.
Answer:

Step-by-step explanation:
Answer:
∠RQS = 21°
∠TQU = 28°
Step-by-step explanation:
90° + 221° + 3x + 4x = 360°
combine like terms:
7x + 311° = 360°
subtract 311° from each side of the equation:
7x = 49°
divide both sides by 7:
x = 7°
∠RQS = 3x = 3(7°) = 21°
∠TQU = 4x = 4(7°) = 28°
