SAT2数学Level 2练习题 Question #2:
What is the range of (x - y) if 3 < x < 4 and -2 < y< -1?
(a) 4< x-y <5
(b) 1< x-y <3
(c) 1< x-y <5

SAT2数学Level 2练习题 Question #3:
A bus travels the distance d from New York to Boston. t1 hours after the bus left New York, a car starts to travel the same distance d from New York to Boston. Both vehicles reach Boston at the same time. Find an expression for d as a function of t1, the speed of the bus v1 and the speed of the car v2.
(a) d = v1t1/(v2 - v1)
(b) d = v1v2t1/(v2 - v1)
(c) d = v1t1/(v2 + v1)
(d) d = v1v2t1/(v2 + v1)
(e) d = v1v2t1
