The

tour

bus

has

traveled

the

first

half

of

your

trip

at

only

30

mph.

How

fast

would

have

to

travel

for

rest

an

average

speed

50

mph?

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

So,

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:]

You are welcome :)
