Step-by-step explanation:
The distance traveled varies directly with the time spent in motion. If d is distance and t is time taken. Then,

or

k is the constant of variation
If d = 150 miles and t = 4 hours

hope this helps :)
Think: 81 and 100 are perfect squares. 95 is between these.
Thus, sqrt(95) is between sqrt(81) and sqrt(100), or between 9 and 10.
The first one is C.
The second one is also C.
