Convert this rate to feet per second. Round your answer to nearest tenth the average speed of a car on a stretch of the interstate is 70 miles per hour.

102.66666667 feet/ seconds

Step-by-step explanation:

From the question, we are told to convert 70 miles per hour to feet per second.

Step 1

1 mile = 5280 feet

70 miles = x feet

Cross Multiply

1 mile × x feet = 5280 feet × 70 miles

x feet = 5280 feet × 70 miles

x feet = 369600 feet

Hence, 70 miles = 369600 feet

Step 2

We convert 369600 feet/ hour to feet per second

60 seconds = 1 minute

60 minutes = 1 hour

1 hour = 60 × 60

= 3600 seconds.

369600 feet/ 1 hour = 369600 feet/3600 seconds

= 102.66666667 feet/ seconds

Therefore, 70 miles per hour is equivalent to 102.66666667 feet/ seconds
