Can someone please help me with this question I need to find the unit rate.

Answer:
You = 50 mph
Friend = 30 mph
Step-by-step explanation:
You = [tex]\frac{250-150}{5-2}[/tex] = [tex]\frac{100}{2}[/tex] = 50
Friend = [tex]\frac{240-120}{8-4}[/tex] = [tex]\frac{120}{4}[/tex] = 30
Use slope formula.
