First find the distance by multiplying 55mi/hr × 1.75 hrs= 96.25mi
Next find the time while traveling at 70mph using this distance. 70 miles/hr = 1hr/70 miles, so multiply 1hr/70mi x 96.25 mi= 1.38 hours
Next find the time while traveling at 70mph using this distance. 70 miles/hr = 1hr/70 miles, so multiply 1hr/70mi x 96.25 mi= 1.38 hours

we know that
in the triangle ABC
∠A+∠B+∠C=180°
find ∠C
∠C=180-[80+65]------> ∠C=35°
Applying the law of sines
AB/sin C=CB/sin A
solve for CB
CB=AB*sin A/sin C-----> CB=45*sin 65/sin 35-----> CB=71.10 ft
the answer is
<span>the distance from person B to the top of the hill is 71.10 feet</span>
