The rate in miles per hour is 30 miles per hour and the car will travel 90 miles in 3 hours
Step-by-step explanation:
Given
Speed of car = rate = s = 44 feet per second
As there are:
1 hour = 60 minutes
1 minute = 60 sec
so there are 60*60= 3600 seconds in an hour.
And it is given that there are 5280 feet in one mile
So the rate in feet per sec will be multiplied with 3600 and then divided by 5280
So,
[tex]Rate = \frac{44*3600}{5280}\\=30\ miles\ per\ hour[/tex]
Miles the car will travel in 3 hours
Putting distance = 3 in rate's formula
[tex]s = \frac{d}{t}\\30 = \frac{d}{3}\\30*3 = d\\d = 90\ miles[/tex]
Hence,
The rate in miles per hour is 30 miles per hour and the car will travel 90 miles in 3 hours
