During a particular trip, how much time had elapsed once 90% of the total distance of the trip had been traveled?
to find how time elapsed to cover 90% of distance we need
time taken (to cover 90% of distance) = \(\frac{total distance}{speed at which the distance is covered}\)
STATEMENT (1)---- The total distance of the trip was 40 miles and the total time elapsed was exactly 4 hours.
total distance = 40 miles
total time taken to cover total distance = 4 hours
speed of traveling = \(\frac{40}{4}\) = 10 miles/hr
90% of distance = 40*\(\frac{90}{100}\) = 36
time taken to cover 90% of the distance = \(\frac{36}{10}\)
SUFFICIENT
STATEMENT (2) The average speed of the trip was exactly 10 miles per hour.
we don't know the total distance hence we don't know what 90% of the distance is
so we cant find the time

OE is E though! Even it was A for me to find how time elapsed to cover 90% of distance we need
