Answer:
a) 2 1/8 miles per hour
b) 8/17 hours per mile
Step-by-step explanation:
To find the rate in mile per hour, divide miles by hours:
(5 2/3 mi)/(2 2/3 h) = (17/3 mi)/(8/3 h) = 17/8 mi/h = 2 1/8 mi/h
__
To find the rate in hours per mile, invert that number:
1/(17/8 mi/h) = 1/((17 mi)/(8 h)) = (8 h)/(17 mi) = 8/17 h/mi
