Problema Solution
If the distance is 10 miles and it takes 1000 seconds to travel the distance, what is the rate in miles per hour?
Answer provided by our tutors
The distance is:
d = 10 mi
The time is 1000 seconds. We need to convert the seconds into hours using the fact that 1 hr = 3600 sec that is 1 sec = 1/3600 hr:
t = 1000 sec = 1000/3600 hr = 5/18 hr
The rate v, in miles per hour (mph) is equal to the distance traveled divided by the time of the travel:
v = d/t
v = 10/(5/18)
v = 36 mph
The rate is 36 mph.
