.
Answer:
1.2 kilometers per minute; 6 kilometers in 5 minutes
Step-by-step explanation:
To find the KM per minute, divide the speed per hour (72) by 60 (minutes in one hour)
72/60 = 1.2 KM per minute
To find the KM for 5 minutes, multiply the KM per minute (1.2) times 5 minutes: 1.2*5 = 6 KM
It would be B. X is on a right angle which is 90 degrees and you must take into thinking that all three angles must be 180. Since it is a mirrored shape, corner E is the same as corner C which is 46.
This adds up to 136 and you must subtract 136 from 180 and is 44.
