The Cave of Swallows is a natural open-air pit cave in the state of San Luis Potosí, Mexico. The 1220-foot-deep cave was a popular destination for BASE jumpers. The function $t=\frac{1}{4}\sqrt{d}$t= 1
4​√d​ represents the time t$t$t​ (in seconds) that it takes a BASE jumper to fall d$d$d​ feet. How far does a BASE jumper fall in 3 seconds?
