An elephant can travel at a constant speed of 25 miles per hour while a giraffe can travel at a constant speed of 16 miles in 1/2 hour which animal runs faster explain your reasoning

The giraffe runs faster

Step-by-step explanation:

Given parameters

Let S1 represent the constant speed of the elephant

Let S2 represent the constant speed of the giraffe

S1 = 25 miles per hour

S2 = 16 miles per ½ hour

Required: Which animal runs faster.

To determine the animal that runs faster, we have to first make sure that the units of speed in both cases are the same.

For the elephant

S1 = 25 miles per hour.

For the giraffe,

S2 = 16 miles per ½ hour

We convert the constant speed of the giraffe to miles per hour

Since speed = distance ÷ time

S2 = 16 miles ÷ ½ hour

S2 = 16 miles * 2 per hours

S2 = 32 miles per hour

By comparison S2 is greater than S1, so the speed of the giraffe is greater than that of the elephant.

Hence, the giraffe runs faster.

This is so because the elephant can cover a distance of 25 miles in 1 hour. Given the same time, the giraffe will cover a distance of 32 miles.

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.

(d)

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.
