Let's call your speed "a"
her walking speed is then "2a"
and her friend's scooter speed is 10 a
let's also call the distance you need to walk "d"
so the time (t)you need is:
d/t=a
t=d/a
and her time is:
t=
(half a distance with the speed of 2a and half a distance (d/2) with the distance of 10 a
now we count (we know that her time is 30 minutes)
30=
//multiply by 20a
600a=
600a=6d/divide by 6
100a=d
Now, in order to calculate your time we need to calculate:
t=d/a
but we know how much is d now!
t=
=100
which means that you need 100 minutes, or 1 h 40 minutes!!!

The length of the time that randy read is 45 minutes.
<h3>What is time?</h3>Time is known to be an element that is often measured or that is measurable.
From the image attached, Randy started reading at 4:10 and Randy finished reading at 4:55.
We therefore need to subtract:
4:55 - 4:10 = 45 minutes
So, Randy is said to read for 45 minutes.
It is a period via which an action, process, etc. is alive or continues such as duration. One can tell the time by counting the minutes and seconds.
