Answer:
A man drove x miles per hour for 3 hours and (2x-60) miles per hour for the next 4.75 hours.Express the total distance traveled in terms of x.
Total distance covered by the man in terms of 'x' = (12.5x-285)miles
Step-by-step explanation:
Given:
Speed of a man = 'x' miles/hour
Time taken = hour
So, distance = product of speed and time.
Distance covered in term of 'x'
Now,
Speed = miles/hour
Time taken= hours
Distance =
=
= miles
Total distance covered by the man = Summation of and
=
= miles
So the total distance covered by the man in terms of 'x' = (12.5x-285) miles.
