2. the amount of time, t, miranda spends cross-country skiing varies directly with the number of miles, m, she skis. suppose miranda skis 2 mi in 0.5 h.
a. write a direct variation equation relating this information.
b. use your direct variation equation from part a to determine how much time it takes miranda to ski 5.2 mi.
3. the length, d, of a violin string varies inversely as the frequency, f, of its vibrations (cycles per second). suppose it is known that a 16-in.-long violin string vibrates 320 cycles per second.
a. write an inverse variation equation modeling this information.
b. use your inverse variation equation from part a to determine the frequency of an 8-in.-long violin string.
