A car is traveling at a steady speed. It travels 2 1/2 miles in 3 1/3 minutes. How far will in 49 minutes? In 1 hour ?


Sagot :

2 1/2 miles / 3 1/3 minutes = 3/4 mile per minute

A. 3/4 mile per minute x 49 minutes = 35 3/4 miles

B 3/4 miles per minute x 60 minutes (1 hour) = 45 miles

Answer:

2 1/2 miles = 5/2 miles

3 1/3 minutes = 10/3 minutes

Here,

in 10/3 minutes travels = 5/2 miles

in 1 minutes travels = (5/2)/(10/3) miles

in 49 minutes travels = (49*(5/2))/(10/3) miles = 36.75 miles

in 60 minutes (1 hour) travels =  (60*(5/2))/(10/3) miles = 45 miles
