Question

An angry teacher saw her student when he was 5200 feet away and started to chase him at a speed of 28 feet per second. The student immediately started to run away at a speed of 24 feet per second. How much time will it take the teacher to catch her student?

Answer 1

1300 s

Explanation:

Distance between teacher and student = 5200 ft .

relative velocity of teacher with respect to student

= 28 - 24 = 4 ft /s

time taken by teacher to catch student

= Distance between teacher and student / relative velocity of teacher with respect to student

= 5200 / 4

= 1300 s .
