I would just punch it in a calculator...
Answer:
<h2>Jasmine will walk 1hr:30min before she catches up to Frank</h2>
Step-by-step explanation:
let the distance of the trail be x
and let the time be t
given that franks average speed is 2 miles per hour
the distance covered by Frank is x-3
the time taken by Frank to cover the distance is
we know that speed=distance/time
2=x-3/t
2t=x-3
x=2t+3---------1
Jasmine speed= 4 miles per hour
speed=distance/time
4=x/t
x=4t--------2
equating 1 and 2 above we have
2t+3=4t
solving for t we have
4t-2t=3
2t=3
t=3/2
t=1.5
That is 1hr 30 min
I think the answer my be B but i am not sure

Answer:
x = 10°; angles are 50°, 46°, 84° (CW from left)
Step-by-step explanation:
The sum of the three angles is 180°, so ...
(6x +10°) +(4x +6°) +(7x +14°) = 180°
17x +10° = 180°
17x = 170°
x = 10°
__
Then the angles are ...
6x -10° = 6·10° -10° = 50°
4x +6° - 4·10° +6° = 46°
7x +14° = 7·10° +14° = 84°
