In a race an athlete runs 1600m at an average speed of 6m/s. The distance is given correct to the nearest 100 metre and the speed correct to the nearest metre per second.
(a) Complete the two statements below.
distance
speed
(b) Calculate the greatest possible time the race could have taken.

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
