The return trip took 1 hour 42 minutes longer
Further explanation:
The distance will remain same on return.
The formula for speed is given by:
Let d be the distance
s1 be the speed while going and s2 be the speed while returning
and
t1 be the time while going and t2 be the time while returning
d=500 miles
s1=60 miles per hour
s2=50 miles per hour
We have to calculate time for both trips,
So,
<u>Time while Going:</u>
<u></u>
<u>Putting the values of d and s1</u>
<u></u>
<u>Converting 8.3</u>
8 will be the hours,
for 0.3 hour
0.3*60=18 minutes
The first trip took 8 hours and 18 minutes.
<u>Time while returning:</u>
Putting the values of d and s1
The difference of both times is: 1 hour 42 minutes
So,
The return trip took 1 hour 42 minutes longer
