Answer 2

Answer:

Option: D is the correct answer.

The expression which  represents Nikita’s distance for the second part of the race is:

              D.    6(0.65 – t)

Step-by-step explanation:

It given that:

Nikita ran a 5-kilometer race in 39 minutes (0.65 of an hour)

Also,  In the first part of her race:

Her speed was 8.75 km per hour and time taken was t

In the second part of the race:

Her speed was 6 kilometer per hour.

So, the distance traveled by her in the second part is:

$Distance=Speed\times Time$

Since we are given speed=6 kilometers per hour

and Time= 0.65-t

( Because she took a total of 0.65 hours and t hour was taken by her in first part)

So the time left is: 0.65-t

Hence, the distance for second part will be:

       $Distance=6(0.65-t)$
