Question 3 (1 point)

Cynthia drove 12 miles in 4.8 minutes. How long would it take her to drive 37 miles? "

Answer 1

D=RT; 12=R*(.08 hours); R=150mph
Now, 37=150*T; T=37/150=14.8 minutes

Answer 2

14.8 minutes

Explanation:

4.8 min/12mi= 0.4 min/1 mile driven

multiply the time by the distance:

37mi*(.4min/1mi), mi cancels and you're left with min

37*0.4=14.8 min
