Answer:
Option A and C
Step-by-step explanation:
First of all we know the speed formula,
[tex]Speed=\frac{distance}{Time}[/tex]
So to find time,
[tex]Time=\frac{distance}{speed}[/tex]
Now let’s find the time of each option
Option a:
Speed = 60 mph
Distance : 120 miles
Time = 120/60
= 2 hours
Therefore option a is correct
Option b:
Speed = 3 mph
Distance = 1.5 miles
Time = 1.5/3
= 1/2 hours
Therefore option b is not applicable.
Option c:
Speed = 80 mph
Distance = 160 miles
Time = 160/80
= 2 hours
Therefore option c is correct.
Option A and C are the answers
