Heather drove at a constant rate. She traveled 162 miles in 3 hours. How far, in miles, did heather travel in one hour?

54 miles

Step-by-step explanation:

Given that Heather travelled at a constant rate, we can deduce that the more the time spend traveling, the more the distance in mile that Heather covers. As such the distance cover varies directly with time. let the distance be d and the time t, this may be expressed mathematically as

d ∝ t

d = kt where k is the constant of proportionality or the rate of travel

162 = k * 3

k = 162/3

= 54 miles per hour

It means Heather covers 54 miles in one hour

54 miles in 1 hour.

Step-by-step explanation:

162 : 3 = 54
