Distance that sound travels through air d varies directly as time t, and d=1,675 ft when t=5 seconds, find t when d=5025ft

divide 5025 by 1675 then whatever you get multiply it by 5 that will get you t when d is 5025

The time, t when d=5025ft given the constant of proportionality is 15 seconds

How to solve direct variation

d = k × t

where,

  • d = distance
  • t = time
  • k = constant of proportionality

d=1,675 ft when t=5

d = k × t

1,675 = k × 5

1,675 = 5k

k = 1,675 / 5

k = 335

Find t when d=5025ft

d = k × t

5025 = 335 × t

5025 = 335t

t = 5025/335

t = 15 seconds
