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. Hi

The new time compared with the old time was increased by multiply 2

Explanation

Velocity is an unit which is the combination from distance divided with time. The international unit from the velocity are km/h and m/s. This unit which is used for measure how the vehicle or people's speed in one particular time (it can be hour or minutes). In the vehicle, there are speedometer which is the function same with the velocity it is to measure how the vehicle speed in one time.

✎ Velocity Formula ✎

The velocity is have a formula to make you know what vehicle speed in the one particular time.

[tex]\boxed{v = \frac{d}{t}}[/tex]

• V as velocity
• D as distance of the vehicle to a place
• T as time to take a way to that place.

✎ Settlement of Question ✎

Known : First distance 50 miles, second distance 300 miles, second velocity is three times fast than first velocity.

Ask : New time compared with the old time ?

Answer :

[tex]v_{2} = 3 \times v{1}[/tex]

[tex]\frac{300}{t_{2}} = 3 \times \frac{50}{t_{1}}[/tex]

[tex]\frac{300}{t_{2}} = \frac{150}{t_{1}}[/tex]

[tex]t_{2} = \frac{300}{150} \times t_{1}[/tex]

[tex]t_{2} = 2 \times t_{1}[/tex]

So, the new time compared with the old time was increased by multiply 2
