I am a math tutor and one of my grade 11 students had this problem the other night. I am stumped and have sought help within my tutoring peers....we feel that there is some information missing.
My student has a test tomorrow and her teacher is absent so I am hoping someone can confirm my assumption or point out what I am missing
2 Fire towers are located 100K apart on high hills. The bearing from T to R is North east. A fire F is observed from tower T at N10degE and from tower R at N75degW. The town of Pretty Valley, at point V, is on a bearing of N25E from T and S70W from R. The observers report the wind is blowing the fire directly toward Pretty Valley at a rate of 8kmh. How many hours do the officials have to evacuate the town?
I know I need to find the distance from F to V. However I cannot see how to get there. My colleague and I are both Bsc Math and we are stumped. I am just hoping it isn't us...maybe they left something out in the text!
