Question

A lion runs at 45 mph and crosses a brigde in 40 seconds. a cheetah crosses the same bridge in 30 seconds. how fast does the cheetah run?

Answer 1

The cheetah runs at a speed of 60 mph.

Step-by-step explanation:

To find out how fast the cheetah runs, we can use the formula:

Speed = Distance / Time

Since both the lion and the cheetah cross the same bridge, the distance they cover is the same. Let's call this distance 'd'.

For the lion, its speed is 45 mph and it takes 40 seconds to cross the bridge. So, we can write:

45mph = d / 40s

Simplifying the equation, we get:

d = 45 * 40 = 1800 miles

Now, let's find the speed of the cheetah. We know that it takes 30 seconds to cross the same distance 'd'. So, we can write:

Speed of cheetah = Distance / Time = d / 30s = 1800 / 30 = 60 mph

Therefore, the cheetah runs at a speed of 60 mph.
