You can put this solution on YOUR website! Pablo is 3 miles behind Marc.
Pablo increases his speed to 5 miles per hour, while Marc, runs at 4mph.
At this rate, how many miles will Pablo have to run to catch up to Marc?
How long will it take?
:
Let t = time for P to catch M
P has to run 3 more miles than M
Write a distance equation; dist = speed * time
5t = 4t + 3
5t - 4t = 3
t = 3 hrs for P to catch M
:
How many miles will P have to run to catch M
3 * 5 = 15 miles
:
:
Check this, find the distance each runs
5*3 = 15 mi
4*3 = 12 mi
------------
diff: 3 mi
