The car's speed is 204.545 miles per hour
Step-by-step explanation:
The given is:
- A race car is traveling at a rate of 100 yards per second
- We need to find the car's speed in miles per hour
∵ The car race is traveling at a rate of 100 yards per second
- At first lets find how many miles are there in one yard
∵ 1 yard = 0.000568182 mile
- Then find how many seconds in one hour
∵ 1 hour = 30 minutes
∵ 1 minute = 60 seconds
∴ 1 hour = 60 × 60 = 3600 seconds
∴ 1 second = [tex]\frac{1}{3600}[/tex] hour
∵ 100 yards per second = [tex]\frac{100yards}{1second}[/tex]
- Multiply the 100 yards by 0.000568182 to change it to miles
and the second by [tex]\frac{1}{3600}[/tex] to change it to hour
∴ [tex]\frac{(100)(0.000568182)}{(1)(\frac{1}{3600})}[/tex]
∴ 100 yards per second = 0.0568182 × 3600
∴ 100 yards per second = 204.545 miles per hour
The car's speed is 204.545 miles per hour
