On monday carla runs 2 5/8 in 15 minutes a. what is s average rate of speed in miles per hour ,for s run? show your work or explain how you know. on tuesday carla decides to jog instead of run and so decreases her average rate of speed by 20 percent b. how many miles does carla noh in 50 minuets on tuesday? show your work and explain how u know.

(a) 10.5 miles/hour

(b) 6.5 miles

Step-by-step explanation:

(a)

Carla runs

time taken by Carla=15 minutes=15/60 hours.

Hence Average rate of speed = total distance/total time

                                        =

Hence, the average rate of speed in miles per hour is 10.5 miles/hour.

(b)

on Tuesday Carla decides to jog instead of walk and decreases her speed by 20%(20/100=0.2).

so her speed=10.5-0.2×10.5

                     =8.4 miles/hour.

Now distance travelled by her in 50 minutes(50/60 hours)=8.4×(50/60) miles

                  =6.5 miles.

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

his first public project he is asked to create a small scale drawing. the garden is a right triangle with base 25m and height 30m. are you trying to solve for the last side/hypotenuse? the irrational form of the answer would be 5\sqrt{61}
