Neil travelled 36km at a speed of 8km/h Grant travelled 48km at a speed of 10km/h whose journey was quickest

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

Neil travelled 36 kilometers at a speed of 8 kilometers per hour.

Divide (the kilometers or "km" will cancel each other out).

Grant

Grant travelled 48 kilometers at a speed of 10 kilometers per hour.

Divide (the kilometers or "km" will cancel each other out).  

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.

when insulating materials rub against each other, they may become electrically charged . electrons , which are negatively charged, may be 'rubbed off' one material and on to the other. the material that gains electrons becomes negatively charged. the material that loses electrons is left with a positive charge.

wind moving at higher speeds will transfer more energy to the water, resulting in stronger waves.
