Answer:

7.5 min/ mile

Step-by-step explanation:

Divide the time taken in minutes by the distance in miles

3 hours = 3 × 60 = 180 mins

3 hours 15 min = 180 + 15 = 195 mins

Average time = \frac{195}{26} = 7.5 min/ mile

75% of a number is 120. What is 40% of the number? A. 36 B. 64 C. 138 D. 225
kakasveta [241]

Answer:

B.64

Step-by-step explanation:

75% of a number is 120.

Let's take "x" be the number.

75% of x = 120

75/100 * x = 120

0.75x = 120

x = 120/0.75

x = 160

So the number is 160.

Now we have to find the 40% of the number 160.

= 40/100 * 160

= 0.4 *160

= 64

40% of the number is B.64

Thank you.
