Explanation

Speed = Distance / Time = 240 miles / 24 minutes = 10 miles per minute

Now, we need to find the time required to cover 650 miles:

Time = Distance / Speed = 650 miles / 10 miles per minute = 65 minutes

So, the correct answer is: 65 minutes

Explanation

To find the percentage of girls, you need to divide the number of girls (28) by the total number of students (20 boys + 28 girls = 48) and multiply by 100:

(28 ÷ 48) x 100 = 58.3%

So, the percentage of girls in the class is 58.3%.

Explanation

To divide a number by 100, you can simply move the decimal point two places to the left.

So, dividing 0.25 by 100 would result in:

0.25 ÷ 100 = 0.0025

Explanation

1*5 = 5

5*4 = 20

20*3 = 60

60*2 = 120

120*1 = 120

Explanation

Convert the time from 9:55 a.m. to 10:15 a.m. to a fraction of an hour:

20 minutes = 20/60 = 1/3 hour

Multiply the rate (40 km/h) by the time (1/3 hour):

40 km/h × 1/3 h = 40/3 km

40/3 km = 13 1/3 km

So, the motorist travels 13 1/3 kilometers.

Explanation

Given: 38 is 20% of a number

Convert the percentage to a decimal: 20% = 0.20

Now, divide both sides of the equation by 0.20:

38 ÷ 0.20 = x

190 = x

So, the correct answer is: 190

Explanation

Explanation

Let the number be x.

Given:

3​/11×x=22

To find x, multiply both sides by3​/11​:

x=22×11/3​=242/3​

But this gives a fractional number — let's double-check:

Actually, it's simpler to find 6/11​ of the number without finding the whole number.

We know:

3​/11​ of number =22

So, 1 part (i.e., $frac{1}{11}$) = 22/3​

Then:

6/11​=6×(22/3​)=132​/3=44
