Stardust the unicorn, covered a distance of 50 miles on his first trip to the forest. on a later trip he travelled 300 miles while going three times as fast. his new time compared to the old time was:

His new time compared to the old time was twice as much.

Step-by-step explanation:

Consider the provided information.

The distance covered in first trip is 50 miles.

The distance covered in later trip is 300 miles.

The relation between speed, time and distance is:

Let speed of the first trip is x.

Thus, the speed of the later trip is 3x.

Now use the above formula by substituting distance 50 and speed as x.

Similarly, time taken in second trip is:

Now, Compare new time with old.

Therefore, his new time compared to the old time was twice as much.

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)

x equals 1

step-by-step explanation:

f(4)=f(×)

x=1
