Question

A commercial shows a truck falling off a cliff. If the cliff is 20 feet long and the 5-foot newscaster casts a 2-foot shadow, how far did the truck fall?

a) 5 feet
b) 10 feet
c) 15 feet
d) 20 feet

Answer 1

The truck fell a distance of 50 feet off the cliff.

Step-by-step explanation:

To find out how far the truck fell, we need to calculate the length of the shadow that the truck casts.

From the given information, we know that the newscaster's height is 5 feet and their shadow is 2 feet. We can use this information to set up a proportional relationship: 5/2 = x/20, where x represents the length of the truck's shadow.

Cross-multiplying, we have 5 * 20 = 2 * x. Simplifying this equation gives us 100 = 2x. Dividing both sides by 2, we find that x = 50 feet.

Therefore, the truck fell a distance of 50 feet off the cliff.
