An airplane is flying from nyc to la. The distance it travels in miles, d, is related to the to the time in seconds, t, by the equation d=0.15t

It will cover 4.5 miles in 30 seconds.

Step-by-step explanation:

An airplane is flying from nyc to la.

The distance it travels in miles,d, is related to the to the time in seconds, t, by the equation :

d=0.15t ...(1)

Let us assume we need to find the distance at t = 30 s.

Put t = 30 s in equation (1).

d=0.15 × 30

d = 4.5 miles

Hence, it will cover 4.5 miles in 30 seconds.

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval
