Marty lives one and a half times further away than Jenny, so must travel one and a half times as quickly. 15mph = 1/2 of Jenny's speed, because Jenny is travelling at 2/3 of Martin's speed. Jenny is therefore travelling at 30mph, and Martin is travelling at 45mph.

To determine which greyhound is faster, we can calculate their speeds. Fluffy travels 15 m in 2 seconds, giving a speed of 7.5 m/s (15 m ÷ 2 s). Tiberius travels 20 m in 3 seconds, resulting in a speed of approximately 6.67 m/s (20 m ÷ 3 s). Therefore, Fluffy is the faster greyhound.

Yes because it travels faster
Because a train is a lot heavier and travels at faster speeds.
Water travels faster through a taller stem because of gravity. The greater height results in increased gravitational potential energy that drives the flow of water through the stem at a faster rate compared to a shorter stem.
A Worm travels faster than a Snail.
lightning travels faster. Light is faster than sound.
well, you can keep the amount of data on it to a minimum, which would make it faster
A whale's song travels faster than a bird's chirp. This is because a whale's song travels through water, where sound moves much faster than it does in air.
Nothing travels faster than light.
Sound travels faster in warmer temperatures. At 30 degrees Celsius, sound will travel faster than at 15 degrees Celsius. This is because sound travels faster in warmer air due to the higher average speed of air molecules.
Because light travels faster than sound.
because sound travels faster in water
I think because it travels faster and it's easier to catch.
