Answer to Question #246327 in Chemistry for keyasia

Question

A lizard is running across the road at a speed of 2.8 m/s. To be safely on the other side of the road, the lizard needs to run 3.0 meters. How long will it take for the lizard to run 3.0 meters? Round to a tenth of a second.

Answer 1

Solution:

speed = 2.8 m/s

distance = 3.0 m

speed = distance / time

time = distance / speed

Hence,

time = (3.0 m) / (2.8 m/s) = 1.07 s = 1.1 s

time = 1.1 s

Answer: 1.1 seconds will it take for the lizard to run 3.0 meters.
