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 with the old time was:

His new time compared with the old time was increased by factor of 2

Acceleration is rate of change of velocity.

a = acceleration (m / s²)v = final velocity (m / s)

u = initial velocity (m / s)

t = time taken (s)

d = distance (m)

Let us now tackle the problem!

This problem is about Kinematics.

In this problem we assume that the unicorn is moving at a constant speed so that the acceleration is zero.

Given:

first distance = d₁ = 50 miles

second distance = d₂ = 300 miles

v₂ = 3 v₁

Unknown:

t₂ : t₁ = ?

Solution:

To find his new time , we will use the following formula.
