Mathematics

Using the given formula speed = distance over time:

Speed = 70 miles / 3 hours

Speed = 23.33 miles per hour

Convert miles per hour to meters per hour:

1 mile = 1609 meters:

23.33 miles x 1690 meters = 37,543.33 meters per hour.


Now convert meters per hour to meters per second:

1 hour = 3600 seconds:

37,543.33 / 3600 = 10.4 meters per second.

If a gym class is divided into 4 equal teams, 2 students have to sit out; 5 teams, 1 student has to sit out; 6 teams, 4 students
Sidana [21]

Answer:

14 students

Step-by-step explanation:

Let x be the number of students, x

  • If a gym class is divided into 4 equal teams, 2 students have to sit out, so x\equiv 2(\rm mod \ 4);
  • If a gym class is divided into 5 equal teams, 1 student has to sit out, so x\equiv 1(\rm mod \ 5);
  • If a gym class is divided into 6 equal teams, 4 students have to sit out, so x\equiv 4(\rm mod \ 6).

From the first congruence,

x=2+4k,

substitute it into the second congruence:

2+4k\equiv 1(\rm mod\ 5)\\ \\4k\equiv -1(\rm mod\ 5)\\ \\4k\equiv -1+5(\rm mod \ 5)\\ \\4k\equiv 4(\rm mod \ 5)\\ \\k\equiv 1(\rm mod \ 5)\\ \\k=5l+1\\ \\x=4(5l+1)+2=20l+6

Substitute this into the third congruence:

20l+6\equiv 4(\rm mod\ 6)\\ \\20l\equiv -2(\rm \ mod 6)\\ \\20l\equiv -2+6\cdot 7(\rm mod\ 6)\\ \\20l\equiv 40(\rm mod \ 6)\\ \\l\equiv 2(\rm mod 6)\\ \\l=6m+2\\ \\x=20(6m+2)+6=120m+46

Since x then x=46\ (\text{when }m=0)

The next number divisible by 4, 5 and 6, greater than 46 and less than 70 is 60, so 14 students should be added.
