Answer:
[tex]\boxed {\tt Neil's \ journey}[/tex]
Explanation:
We want to find who travelled faster, so we must find the time for each person's journey. Time can be found by dividing distance by speed.
Neil
[tex]t=\frac{d}{s}[/tex]
Neil travelled 36 kilometers at a speed of 8 kilometers per hour.
[tex]d= 36 \ km \\s= 8 \ km/hr[/tex]
[tex]d=\frac{36 \ km}{8 \ km/hr}[/tex]
Divide (the kilometers or "km" will cancel each other out).
[tex]d=4.5 \ hr[/tex]
Grant
[tex]t=\frac{d}{s}[/tex]
Grant travelled 48 kilometers at a speed of 10 kilometers per hour.
[tex]d= 48 \ km \\s= 10 \ km/hr[/tex]
[tex]d=\frac{48 \ km} { 10 \ km/hr}[/tex]
Divide (the kilometers or "km" will cancel each other out).
[tex]d=4.8 \ hr[/tex]
Neil's journey took 4.5 hours and Grant's took 4.8 hours. We want to find the journey that was quicker and 4.5 is less than 4.8. So Neil's journey was quicker.
