Question

Kari has been driving at a constant speed for the last hour. If Kari is traveling at a speed of 65 miles per hour, which equation best represents the relationship between time in hours, t, and distance in miles, d?

d = 65t


t = d + 65


t = 65d


d = t + 65

Answer 1

(a) d=65t

Explanation:

If, for example she drove 10 hours, and she drove 65 miles each hour:

d=?

t= 10 hr

Speed= 65 mph

The formula for distance (check triangle linked below) is d=st (s*t)

so,

d=65t

hope this helps. It really simple, But I don't think I explained it too well.

Answer 2

Answer: a) d=65t
distance=65mph• hours driven
