Question

11 bronte walks 1.5 miles on a trail. then he jogs at a speed of 5 miles per hour. bronte’s total distance walking and jogging is 5.25 miles. how long does he jog? show your work.

Explanation:

Step1: Find jogging distance

Total distance is 5.25 miles, walking distance is 1.5 miles. So jogging distance $d = 5.25 - 1.5 = 3.75$ miles.

Step2: Use speed formula to find time

Speed formula: $v=\frac{d}{t}\implies t = \frac{d}{v}$. Speed $v = 5$ mph, distance $d = 3.75$ miles. So time $t=\frac{3.75}{5}=0.75$ hours.

Answer:

0.75 hours (or 45 minutes)
