100 - 83.5 = 16.5 [three significant figure]
2.45 + 18.3 = 20.75 [four significant figures]
Option b is correct.
In the given problem the best hint that is given for getting to the answer is that Evan's family drove at the same speed each day.
Then
On the first day the speed of the car = Distance/time
= 300/6
= 50 miles/hour
Then for calculating the distance traveled on the third day = speed * time
= 50 * 3
= 150 miles
Then on the third day they arrived at the park by driving 150 miles in 3 hours. So the correct option is option "C".

Dana made 96 strides.
Step-by-step explanation:
Given,
Ratio of Sally's stride to Dana's strides = 5:4
Strides made by Sally = 120
Let,
x be the strides made by Dana.
Ratio of Sally to Dana = 120:x
Using proportion;
Ratio of Sally's stride to Dana's stride :: Ratio of Sally to Dana

Product of mean = Product of extreme

Dividing both sides by 5

Dana made 96 strides.
