Mrs. Wood is going to the desert during Thanksgiving break. If she drives 120 miles in 2 hours, how many
more miles are left if she has to drive for another 5
hours at a proportional rate?

she has to drive another 300 miles

Step-by-step explanation:

120/2=60 so 60*5=300

300 miles left

Step-by-step explanation:

here's why if she is driving already 2 miles which is 120 and she is going to to drive for 5 hours, 5 hours is 300 miles which that means she has left 300.

- "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."

94

step-by-step explanation:

average the numbers and use a variable to figure out the minimum to get a 90.

(79+94+91+92+x)/5=90

x = 94
