Answer 1

Answer:

The time is 1.967 hours.

Step-by-step 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

$\text{Distnace}=\text{Speed}\times \text{Time}$

The distance is 200 miles.

The speed of car is 101.7024 miles per hour.

Substitute the value sin the formula,

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

$\text{Time}=\frac{200}{101.7024}$

$\text{Time}=1.9665$

Nearest thousandth of an hour is 1.967 hours.

Therefore, The time is 1.967 hours.
