Answer:

The answer is 198 feet.

Explanation:

You convert 45 miles/ hour to feet/ hour:

45 × 5,280 = 237,600 feet/ hour

Now you remember that there are 60 minutes in an hour, and 60 seconds in a minute. We divide 237,600 feet per hour by 60 to get feet/ minute:

237,600 ÷ 60 = 3,960 feet per minute

You just have to divide 3,960 by 60 to get back to feet/ second:

3,960 ÷ 60 = 66 feet per second

Now you know how fast the car can travel (in feet) in a second. Now to find out how many feet it travels in 3 seconds, you just multiply 66 by 3:

66 × 3 = 198 feet which is the final answer.

Answer: 880

Step-by-step explanation: We use unit rates to convert miles per hour to feet per second

60 miles/ hour × 5280 feet/mile × 1 hour/ 60 minutes × 1 minute/ 60 seconds = 88 seconds

So the distance in 10 seconds is 10×88 = 880
