5. A car that travels 20 miles in

a car that travels 30 miles
hour at constant speed is traveling at the same speed as
ar at a constant speed. Explain

Answer 1

Question:

A car that travels 20 miles in 1/2 hour at constant speed is traveling at the same speed as a car that travels 30 miles in 3/4 hour at constant speed. Explain

Answer:

Both the car travels at the same speed of 40 miles per hour .

Explanation:

Given:

car 1 :

Distance travel car 1 travels =20 miles

Time taken = 1/2 hour

car 2 :

Distance travel car 1 travels =30 miles

Time taken = 3/4 hour

Solution:

Let the speed at which car 1 travels be x

Let the speed at which car 2 travels be y

Finding the speed of car 1 :

Speed of car 1,
`x =(distance)/(time)`

=>
`x=(20)/(((1)/(2)))`

=>
`x=20* (2)/(1)`

=>x = 40 miles per hour

Finding the speed of car 2 :

Speed of car 2,
`y =(distance)/(time)`

=>
`y=(30)/(((3)/(4)))`

=>
`y=30* (4)/(3)`

=>
`y=(120)/(3)`

=>x = 40 miles per hour
