On an average day, a garden snail can travel about 0.05 mile. The snail travels 0.2 times as far as the average distance on day
daser333 [38]

Answer: 0.04 miles

 

SOLUTION

 

Given,

Average daily distance of a garden = 0.05 mile.

 

Distance traveled on day 1 = 0.2 times as far as the average distance

= 0.2 x 0.05 miles

= 0.01 miles

 

Distance traveled on day 2 = 0.6 times as far as the average distance

= 0.6 x 0.05 miles

= 0.03 miles

 

Total distance traveled in two days

= Distance traveled on day 1 + Distance traveled on day 2

= 0.01 miles + 0.03 miles

= 0.04 miles
