A hurricane has moved 255 miles in 6 hours.

initial speed = 255 miles / 6 hours = 42.5 mph



Beginning with the time-speed-distance formula, solve for speed

Part II


Compute the initial speed of the hurricane using the time-speed-distance formula




speed increases by 10%

10% of 42.5

= .10 * 42.5

= 4.25 mph

final speed after 10% increase

final speed = 42.5 + 4.25

final speed = 46.75 mph


Compute the final speed of the hurricane after the 10% increase in speed

Part III



How far will the hurricane travel in the next 4 hours ?

distance = 46.75 mph * 4 hours

distance = 187 miles


Compute the distance the hurricane travels in four hours (after the 10% increase in speed)





Final Answer:

distance = 187 miles



 Final Answer:  the distance the hurricane travels in four hours (after the 10% increase in speed)
