Answer 1

The time is 1.967 hours.

Explanation:

Given : The winner of a 200 mile race drove his car to victory at a rate of 101.7024 mph.

To find : What was his time​ (to the nearest thousandth of an​ hour)?

Solution :

The relationship between distance, speed and time is

`\text{Distnace}=\text{Speed}* \text{Time}`

The distance is 200 miles.

The speed of car is 101.7024 miles per hour.

Substitute the value sin the formula,

`\text{Time}=\frac{\text{Distnace}}{\text{Speed}}`

`\text{Time}=(200)/(101.7024)`

`\text{Time}=1.9665`

Nearest thousandth of an hour is 1.967 hours.

Therefore, The time is 1.967 hours.
