The answer for this question is “A”
So this is not too hard, as with any math problem we write what we know.
Starting speed: 80km/h
Time from P to Q: 2.5h
Increase in speed: 20km/h (25% is dividing by 4)
Distance from Q to R: 150 kilometers
So let's find the speed and distance for both legs of the trip.
Speed for P to Q: 80km/h
Distance from PtoQ: 200km (2.5h * 80km/h)
Speed from Q to R: 100km/h (80 +20)
Distance from QtoR: 150km.
Now we multiply the speeds by their respective distances add them and then divide by the total distance.
((80 *200) + (100 * 150))/350 = ~88.57143

Answer: 10/16</h3>
===========================================================
Explanation:
All of the answer choices are fractions with 16 as the denominator. We can compare the numerators to see which is largest. In that case it's 10, so 10/16 is largest.
-----
You can use a calculator to find the decimal value of each fraction
4/16 = 0.25
3/16 = 0.1875
8/16 = 0.5
10/16 = 0.625
and we can see that 0.625 is largest so 10/16 is largest
