(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.
