The ratio of tulips to roses is 17/11. if there are 3444 tulips and roses in the garden, how many are tulips?

You can also approach it this way:

28 flowers times n = 3444

so n = 123

11 x 123 = roses, 17 x 123 = tulips.

Those 2 products should add up to 3444. They do. :-)

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
