Answer:
Jim spent approximately 2.24 hours on the bicycle.
Step-by-step explanation:
To find the amount of time Jim spent on the bicycle, we can use the formula:
Time = Distance / Speed
We know that Jim's total trip took 5 hours and that the distance of the trip was 168 miles. Let's assume that Jim spent x hours on the bicycle.
When Jim was riding his bicycle, he covered a distance of x miles at a speed of 37 miles per hour. Therefore, the time spent on the bicycle can be calculated as:
x = Distance / Speed
x = x miles / 37 miles per hour
After the bicycle chain broke, Jim had to walk the remaining distance of (168 - x) miles. Walking at a rate of 3 miles per hour, the time spent walking can be calculated as:
5 - x = (168 - x) miles / 3 miles per hour
Now, we can solve these equations to find the value of x, which represents the time spent on the bicycle.
x = x / 37
5 - x = (168 - x) / 3
By solving these equations simultaneously, we can find that x is approximately 2.24 hours.
