If it took Carlos 1/2 hour to cycle from his house to the library yesterday, was the distance that he cycled greater than 6 miles? (note: 1 mile = 5280 feet)
(1) The average speed cycled was greater than 16 ft/sec
(2) The average speed cycled was less than 18 ft/sec
ANSWER --> (1) and (2) together are not sufficient.
The trick here is seeing if the greater than and less part of the answer suffices to figure out of he cycled more than 6 miles. But I figured this out by doing the whole equations out, ie converting ft/sec to ft/min, then multiplying by 30 mins, then converting ft into miles. I did this for both statements, but is there a quicker way?
