So there’s something called the Triangle Inequality Theorem,
He would have saved 30 minutes because to go the same distance as 120 Km/h for 3 hours and 30 minutes amounts to 420 km. If he drove faster at 140 km/h he would have reached 420 km in 3 hours instead of 3 hours and 30 minutes.
Answer:
Its too blurry, I cant even read it sorry :(
Step-by-step explanation:
<h2>
The number is "a".</h2>
<h2>
Five more than "a"</h2>
⇒ a + 5 //Add 5 to a
<h2>40% of "a"</h2>
⇒ 40% x a //Find 40% of a
⇒ 0.4 x a //Convert 40% to decimal
⇒ 0.4a //Multiply them together
<h2>40% more than "a"</h2>
⇒ a + 0.4a //The the answer we found earlier to a
⇒ 1.4a //And that is the answer
<h2>
ANSWER: 1.4a</h2>
