Respuesta :
Using the relation between velocity, distance and time, it is found that the average speed of the record winner of the wheelchair division was of 20.04 miles per hour.
What is the complete question?
"The record for the Boston Marathon’s wheelchair division is 1 hour,
18 minutes, and 27 seconds.
The Boston Marathon is 26.2 miles long. What was the average speed of the record winner of the wheelchair division?"
What is the relation between velocity, distance and time?
Velocity is distance divided by time, that is:
v = d/t.
For this problem, we have that:
- The distance is of 26.2 miles.
- The time in hours, considering an hour has 3600 seconds and a minute has 60 seconds, is given by: t = 1 + (18 x 60 + 27)/3600 = 1.3075.
Hence the velocity is given by:
v = 26.2/1.3075 = 20.04 miles per hour.
The average speed of the record winner of the wheelchair division was of 20.04 miles per hour.
