Thank you for the opportunity to help you with your question!
Let the speed in the second half of the trip be x.
Let the total distance be d.
Let the time taken for the first half of the trip be t
and the time taken for the first half of the trip be t' .
We know that
For the first half of the trip,
Distance = d/2
Speed = 30 mph
Time = t
For the second half of the trip,
Speed = x
Time = t'
Total time taken for the trip = t + t' =
It is required that average speed for the trip be 50 mph.
So, again using the formula for speed, we get
So the bus should travel at 150 mph for the second half of the trip.
this is not correct
lol yes it is, apologies and thank you:]
