Answer:
3.6 miles in 90 mins
Step-by-step explanation:
REMEMBER PROPORTIONS
SO IN THIS CASE THIS IS HOW YOU WRITE IT:
[tex]\frac{2 miles = 50 mins}{x=90 mins}[/tex]
So this means in 50 minutes he covered 2 miles and in 90 minutes she covered x miles.
To find x cross multiply :
2 miles * 90 = 180 and x * 50 = 50x
That means 180 = 50x
Divide both sides by 50:
[tex]\frac{180}{50}[/tex]=[tex]\frac{50x }{50}[/tex]
3.6 = x
180 divided by 50 is 3.6 and 50x divided by 50 is x.
THUS HE TRAVELLED 3.6 MILES IN 90 MINUTES.
