Answer:
58.3
Step-by-step explanation:
58.3 has the highest unit (the number left of the dot)
D=RT
313.5=R4
divide by four
313.5/4=78.375
Therefore the answer is B
When solving these types of problems just ignore the “shorter leg” or “longer leg” and focus on the lengths. Pythagorean’s Theorem is used in this problem. Since a leg and hypotenuse length are given then you you set the problem up as 9^2+b^2=15^2. You then do the squares so that it is shown as this, 81+b^2=225. Next you need to subtract 81 on both sides of the equation to isolate the variable b (or the missing leg length) which leaves you with b^2=144. Next to isolate the variable completely you do the square root of both b^2 and 144 which leaves you with the answer b=12. The leg is 12cm long.
1.5 hours is half of 3
so 1.5+1.5=3 and 2.4+2.4=4.8
That person can walk 4.8 miles in 3 hours
