Answer:
D
Step-by-step explanation:
If you multiply 3 and 7 you are saying she worked 21 hours when she only worked a total of 10 hours.
The truck was going 40 miles per hour
The amount of time was 2 hours:
(90-80: 10)(10/2=5)
80 divided by two is 40
The car was going 45 miles per hour
(90-80:10)(10/2=5)
90 divided by two is 45
