Can someone please be generous & help me out on this problem

Rate of Change:

At 1 mile in 30 seconds.

At  5 miles in 2.5 minutes.  2.5 minutes = 2.5*60 = 150 seconds.

Rate of change =   Change in height / Change in time

                           =   (h₂-h₁)/(t₂-t₁)

                           =   (5 -1) /(150 -30) = 4/120 = (1/30) = 0.0333 miles per second.

                            = (1/30) miles per second or 0.0333 miles per second.

To have the answer in miles per minute.

        (1/30) miles per second = (1/30) miles/second.

60 seconds = 1minute

1 second = (1/60) minute.

(1/30) miles/second  =  (1/30) miles/(1/60)minute

                                  =   (1/30) *60 miles / minute

                                  =    2 miles per minute.

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles

1. 180°. the sum of the interior angles of a triangle is 180°, for the equilateral triangle that it has three equals side is 60°+60°+60°=180°.

2. 60°. each interior angle of a equilateral triangle is 60°

3. 120°. the measure of ∠m is 120°, the sum of the angles ∠m and ∠n is equal to 180°. so, in order to find the measure of ∠m, we have ∠m+∠n=180° > ∠m=180°-∠n > ∠m=180°-60°=120°.

4. 360°. the sum of the exterior angles of an equilateral triangle is ∠m+∠r+∠x=120°+120°+120°=360°. the exterior angles of any triangle always add 360°.
