Answer:Lucas is faster
Step-by-step explanation:
Distance = speed × time
Time = distance × speed
the path from the bottom to the top of the mountain was 2 miles.
James climbed at an average rate of 3 mph. This means that the time it took James to climb to the top of the mountain would be
2/3 hours
James ran back at 4 mph. This means that the time it took James run back to the bottom of the mountain would be
2/4 = 1/2 hours
Total time that James spent would be
2/3 + 1/2 = 7/6 = 1.7 hours.
Lucas climbed at an average rate of 2 mph. This means that the time it took Lucas to climb to the top of the mountain would be
2/2 = 1 hour
Lucas ran back at 5 mph. This means that the time it took Lucas to run back to the bottom of the mountain would be
2/5 hours
Total time that James spent would be
1 + 2/5 = 1.4hours.
Answer:
James is faster
Step-by-step explanation:
It took 70 minutes for James to finish and 84 minutes for Lucas to finish and James was faster.
Step-by-step explanation:
Keep in mind that Distance = Speed * Time
First lets starts off with James,
Climbing rate of James = 3 mph
Running back rate of James = 4 mph
Total time taken by James = 3/4 x 2/4 = 14/12 = 7/6
Lets convert that into min to make it easier,
7/6 x 60 = 70 min
Now, lets look at lucas,
Climbing rate of Lucas = 2/2 = 1 hour(s) or 60 minutes
Climbing back rate of Lucas = 2/5 of an hour
Now lets convert this one into minutes,
2/5 x 60 = 24 minutes
Total time taken by Lucas = 24 + 60 = 84 minutes
so that means
James = 70 minutes
Lucas = 84 minutes
Therefore James was faster
Hope this helped and please correct me if I got something wrong :)
