The odd natural number which is mentioned as X is 175.

<u>Step-by-step explanation:</u>

  • By prime Factorization method .
  • Step 1  : The prime factor for 40 is = 2×2×2×5.
  • Step 2 :The prime factor for 1400 is = 2×2×2×5×5×7.
  • Step 3 : the prime factor for the unknown  natural odd number is to be find by comparing the factors of 40 and 1400.
  • Step 4 : Lcm is known as least common multiple.
  • Step 5 : Thus we can see  the 5×5×7 in 1400 as different factors from the factors of 40.
  • Step 6 : So lets multiply the factors we get number 175 which satisfies the condition of the odd number.
  • Step 7 :  The prime factors of 175 are 5×5×7.

kadeem and quinn both drive 25 miles. Kadeem drives at a constant speed of 50 miles an hour. Quinn drives at a constant speed of
Phantasy [73]

Answer:

Kadeem will take 0.166 h more to complete the course.

Step-by-step explanation:

The speed is the rate at which the distance changes, when the speed goes up the distance changes more quickly, therefore if the distance is the same and the speed is higher the one who will take longer is the one that has less speed. In this case the one who will take longer to drive the 25 miles is Kadeem, since he's driving at 50 mph. In order to calculate how much longer we need to calculate the time at which each of them complete the course, this is shown below:

time = distance/speed

For Kadeem:

time = 25/50 = 0.5 h

For Quinn:

time = 25/75 = 0.334 h

The difference between the is 0.5 - 0.334 = 0.166 h.
