Answer:frog 1

Step-by-step explanation:

Frog 1 jumps 80cm in 5 sec

Frog 2 jumps 15cm in 1 sec

The rule says each frog must cross the finish line which is 5m away to win the race

If Frog 1 jumps 80cm in 5 sec, then frog 1 jumps 80/5 = 16cm in 1 sec

Converting from cm to m

1 m = 100cm

For frog 1, 16cm = 15/100 = 0.16m

For frog 2, 16cm = 15/100 = 0.15m

Frog 1 takes 5/0.16 = 31.25 sec to run the finish line

Frog 2 takes 5/0.15 = 33.33 sec to run the finish line

So frog 1 will win the race

Sam takes x minutes yo walk from home to library and 5 minutes more to walk from the library to school than fron home to the lib
LuckyWell [14K]

Answer:

2x+5\ minutes

Step-by-step explanation:

Given:

Sam takes x minutes yo walk from home to library.

And takes 5 minutes more to walk from the library to school than from home to the library.

Express the total time taken for Sam to walk from home to school via the library in terms of x.

<u>Solution:</u>

Time taken by Sam to walk from home to library = x\ minutes

Time taken by Sam to walk from library to school = x+5\ minutes

Total time taken by Sam to walk from home to school via the library = Time taken to walk from home to library + Time taken to walk from library to school

Total time taken = x+x+5=2x+5

Therefore, the total time taken for Sam to walk from home to school via the library is 2x+5\ minutes
