Answer: It took 70 minutes for James to finish and 84 minutes for Lucas to finish and James was faster.
Step-by-step explanation:
Given,
Climbing rate of James = 3 mph
Running back rate of James = 4 mph
Climbing rate of Lucas = 2 mph
Running back rate = 5 mph
Total distance = 2 miles
We know that;
Distance = Speed * Time
As we have to find, we will rearrange the formula in terms of time
Time took by James for climbing =
Time took for running back =
Total time =
Total time taken by James =
1 hour = 60
Total time taken by James =
Time took by Lucas for climbing =
Time took by Lucas for climbing = 60 minutes
Time took on return =
Total time taken by Lucas = 60+24 = 84 minutes
Therefore,
It took 70 minutes for James to finish and 84 minutes for Lucas to finish and James was faster.
it took 70 minutes for james to finish which mean he finished faster bc lucas finished after james and it took lucas 84 minutes
