The least number of rolls needed

= 5 rolls

Step-by-step explanation:

Area = length x width

A = l x w

A = 15 x 2.5

A = 37.5 ft²

If 37.5 ft² = 1 roll

What about 200 ft² = ?

= (200 x 1) ÷ 37.5

= 200 ÷ 37.5

= 5.33°

Least number of rolls. = 5 rolls

5

step-by-step explanation:

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
