Answer:africa
Step-by-step explanation:
science
first off, let's notice that Purple's time is in minutes, whilst the rate is in miles per hour, the units of both must correspond, so, we can either change the time from minutes to hours or the rate from hours to minutes, hmmm let's change the time to hours.
so 40 minutes, we know there are 60 minutes in 1 hour, so 40 minutes will be 40/60 of an hr, or namely 2/3.

I believe the answer to that problem would be $68.55, since you have to add them together and then multiply them by .07 for the percentage.
Answer:
B. 60 degrees
Step-by-step explanation:
∠6 corresponds to ∠3, which is supplementary to ∠2.
∠6 = 180° -∠2 = 180° -120°
∠6 = 60°
