Follow the rules of PEMDAS:
42/(15-8)
42/7

The aides of a right triangle will always satisfy the Pythagorean relationship ...
a² + b²= c²
We can take each of these and try it out:
(1) ... 10² + 24² = 100 + 576 = 676
√676 = <em>26 Yes</em>.
(2) ... 12² + 18² = 144 + 324 = 468
√468 = 21.6, not 20. <em>No.</em>
(3) ... 15² + 26² = 225 + 676 = 901
√901 = 30.017 Awfully close. As an engineer, I'll buy this one. <em>Yes.</em>
(4) ... 40² + 50² = 1,600 + 2,500 = 4,100
√4,100 = 64.03, not 80.<em> No.</em>
(B) 4 hr is the correct answer.
<h3><u>Explanation</u> :</h3>
★ Speed of body is defined as the ratio of distance travelled to the time taken
Given that,
distance = 56 miles
speed = 14 miles per hour
<u>By</u><u> </u><u>subs</u><u>tituting</u><u> </u><u>the</u><u> </u><u>values</u><u>,</u><u> </u><u>we</u><u> </u><u>get</u>
⭆ time = distance/speed
⭆ time = 56/14
⭆ <u>time = 4 hr</u>
