Answer:
d= 75*t
Explanation:
Given data
We are given that the total distance = 270 miles
And that they have already traveled 42 miles
speed= 75mi/h
The remaining distance of the journey is = 270-42
= 228 miles
We know that
speed= distance/time
distance= speed*time
also
d= 75*t
Hence, we can estimate the distance they have traveled for any number of time t
