Aairplane travels at 150 miles per hour the number of hours at that rate is h what is an expression for the number of miles traveled?

150h

Step-by-step explanation

An expression doesnt have an equal sign. If it was an equation it would have an equal sign and be m=150h.

FYI: m stands for miles traveled

- "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."
