Sam left his school at 3: 05. he walked at a speed of 3.2 mph. 15 minutes later, al started running after him, and he caught up with sam 10 minutes later. what was al’s speed?

8 miles per hour (mph)

Step by step explanation:  

Given that,

Sam left his school at 3:05

Walked at a speed of 3.2 mph

Al’s speed = ?

AI caught up with Sam 10 minutes later

Speed = distance /time

Sam’s distance  

3.2 x 1/4 = 0.8 miles

At the same time, Al runs for 10 min, which is 1/6 hr.  

Meanwhile in the same 10 minutes, Sam walks 3.2 x 1/6 =0.53 miles.

AI ran the distance of -> 0.8+ 0.53 = 1.3 miles  

According to the above formula  

1/3 divided by 1/6 = 4/3  

4/3 * 6 = 24/3 = 8 mph
