Question 1164552
he has to drive at 60 miles per hour or less.
assuming he drives at 60 miles per hour, then
60t + 36 = 300 gets you t = 4/4 hours.


A is no good because he can easily do it in less than 7 hours.
D is no good because you don't know when he started and so there's no way of knowing whether he can make it by the end of the day of not.
C is no good because, if he travels at 60 miles per hour, it will take him 4.4 hours to reach 300 miles.
the only way he can do it in 4 hours is to travel more than 60 miles per hour.
for example:
x * 4 + 36 = 300
x is the speed
4 is the time in hours.
you get 4x = 264
solve for x to get x = 66
that's above 60 miles per hour which means he has to go over the speed limit to achieve that.



i would say B is the best fit.
he could do 300 miles in 4.4 hours.
if he traveled less than 60 miles per hour, he could make 300 miles in 5 hours.
for example:
x * 5 + 36 = 300
x is the speed
5 is the time in hours
you get 5x = 264
solve for x to get x = 264/5 = 52.8 miles per hour.
that's below and close to 60 miles per hour.
it seems the most reasonable.
