Final answer:
To find the unit rate of Jamie's bike riding speed, divide the total distance (124 miles) by the total time (73 hours), giving an average speed of 1.70 miles per hour when rounded to two decimal places.
Step-by-step explanation:
The student has asked how to find the unit rate at which Jamie rode his bike, given that he rode 124 miles in 73 hours. To find the unit rate, which is the speed in miles per hour, you need to divide the total distance by the total time.
Here is the step-by-step calculation:
Write down the total distance ridden: 124 miles.
Write down the total time taken: 73 hours.
Divide the distance by the time to find the unit rate (speed):
124 miles ÷ 73 hours = 1.6986 miles per hour.
If we round the unit rate to two decimal places, Jamie rode his bike at an average speed of 1.70 miles per hour.
