A hiker walking at a constant rate of 4 miles per hour is passed by a cyclist traveling in the same direction along the same pat

erastovalidia [21]

Answer: the cyclist must wait for 25 minutes until the hiker catches up.

Step-by-step explanation:

Distance = speed × time

The Cyclist was travelling in the same direction along the same path

as the hiker at a constant rate of 20 miles per hour. If the cyclist stops to wait for the hiker 5 minutes after passing her, then the distance that the cyclist travelled in 5 minutes(5/60 hour) is

20 × 5/60 = 100/60 miles

For the hiker to catch up with the cyclist, she would cover 100/60 miles at a speed of 4 miles per hour.

Time = distance/speed

Time required by hiker to catch up with the cyclist is

(100/60)/4 = 100/240 hour

Converting 100/240 hour to minutes, it becomes

100/240 × 60 = 25 minutes

There are between 24 and 40 students in a class.

patriot [66]

Given:

There are between 24 and 40 students in a class.

The ratio of boys to girls is 4:7

To find:

The number of students in the class.

Solution:

Let the number of boys are girls are 4x and 7x respectively, where, x must be a positive integer because number of boys and girls is always a positive integer. Then, the total number of students is

$\text{Total students}=4x+7x$

$\text{Total students}=11x$

It means total number of students is multiply of 11.

Multiples of 11 are 11, 22, 33, 44, ... . So, multiples of 11 between 24 and 40 is 33.

Therefore, the total number of students in the class is 33.

One month,Jill worked 2 more hours than Ivan,and Susie worked three times as many hours as Jill. Together they works 48 hours. F

vovikov84 [41]

Let us assume Ivan worked = x hours.

Jill worked 2 more hours than Ivan.

Therefore, jill worked = x +2 hours.

Susie worked three times as many hours as Jill.

Therefore, Susie woked 3 times of number of hours of Jill = 3(x+2).

Total number of hours they worked together = 48 hours.

Number of hours Ivan worked + Number of hours Jill worked + Number of hours Susie worked = 48.

Therefore,

x+ x+2 + 3(x+2) =48.

Distributing 3 over (x+2), we get 3x +6.

Therefore,

x+ x+2 + 3(x+2) =48

=> x+x+2+3x+2 = 48.

Combining like terms, we get

5x + 4 = 48.

Subtracting 4 from both sides, we get

5x + 4-4 = 48-4.

5x = 44.

Dividing both sides by 5, we get

x= 44/5 hours or 8 4/5 hours.

Therefore, Ivan worked = 8 4/5 hours.

Jill worked = x +2 hours = 8 4/5 hours + 3 = 11 4/5 hours.

Susie woked = 3 (x+2) = 3 (44/5 +2 ) = 3(54/5) = 162/5 hours or 32 2/5 hours.
