Question

a car travels 30 1/5 miles in 2/5 of an a hour. what if the average speed, in miles, per hour of the car?

Answer 1

Average speed = 30.2 miles / .4 hours =

75.5 mph

Explanation:

Answer 2

Average speed of the car is
`75.5\text{ miles per hour}`.

Explanation:

We are given the following information:

Distance traveled by the car =

`30\displaystyle(1)/(5)\text{ miles}`

Time taken by the car =

`\displaystyle(2)/(5)\text{ hours}`

Formula:

Speed =
`\displaystyle\frac{\text{Distance covered}}{\text{Time taken}}`

Putting all the values,

`\text{Speed} = \displaystyle(30(1)/(5))/((2)/(5)) = ((151)/(5))/((2)/(5)) = (151)/(2) = 75.5\text{ miles per hour}`

Average speed of the car is
`75.5\text{ miles per hour}`.
