Keenan will run 2.5 miles from his house to Jared’s house. He plans to hang out for 45 minutes before walking home. If he can run at 6 mph and walk 4 mph, how long will he be from home?

Kennan will be from home approximately an hour and 48 minutes.

Step-by-step explanation:

We must know that total time () that Keenan will be from home is the sum of run (), hang out () and walk times (), measured in hours:

If Keenan runs and walks at constant speed, then equation above can be expanded:

Where:

, - Run and walk distances, measured in miles.

, - Run and walk speeds, measured in miles per hour.

Given that , , and , the total time is:

()

Kennan will be from home approximately an hour and 48 minutes.

2 x^2 -3x+p

sum of roots = 3/2

let other root be x

3+ x = 3/2

x= 3/2 - 3 = -3/2

product of roots = p/2

3× -3/2 = p/2

-9 = p
