The sixth grade class from franklin middle school is going to the zoo on a field trip. there are 270 students who want to go on the field trip. if the school requires one adult for every 15 students, how many adults will be needed for the field trip?

18

Step-by-step explanation:

To find the number of adults required, take the number of students and divide by 15

270/15 =18

We require 18 adults

898.1666667

step-by-step explanation:

5389/6 = 898.1666667

- "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."
