Answer:
1.34 feet/seconds
Explanation:
Looking at the above question, we would be converting 55 miles per hour to feet per seconds.
From the above question, we are given the following conversion values
1 minute = 3,600 seconds
1 mile = 5,280 feet
55 miles per hour = 55 mile / 1 hour
So,
If 1 mile = 5,280 feet
55 miles = x feet
We cross Multiply
x = 5,280 × 55
x = 290,400 feet
Hence, 55 miles = 290,400 feet
1 hour = 60 minutes
If 1 minute = 3,600 seconds
60 minutes = x seconds
We cross multiply
x = 60 × 3,600
x = 216,000 seconds.
This means
60 minutes = 216,000 seconds
In other to find out how fast is the car is,
Speed = Distance / Time
Speed = 290,400 feet/216,000 seconds
Speed = 1.3444444444 feet/seconds
To the to the correct number of significant figures, the car is traveling at 1.34 feet per second.
