Question

Distance between 2 airports = 1,450 miles

average speed of airplane = 350 mph
Travel time by bus after arrival at airport = 30 minutes
Total time travel = _____ hours

A. 4.44
B. 4.14
C. 4.64

Answer 1

Firstly, there is an airplane flight.

1450 miles / 350mph = 4.14h

Secondly, there is a bus travel.

4.14h + 0.5h = 4.64h

The answer is C.

Answer 2

`4.14h+0.5h=4.64h`

Explanation:

It is given that Distance between 2 airports is 1,450 miles and average speed of airplane is 350 mph.

Travel time by bus after arrival at airport = 30 minutes

Now, Firstly there is an airplane flight, thus time taken by airplane will be:

`t_(1)=\frac{1450\text{miles}}{350\text{miles per hour}}=4.14\text{hour}`

Secondly, there is a bus travel., thus Travel time by bus after arrival at airport is:

`t_(2)=30\text{minutes}`

Therefore, total time taken in travel=time taken by airplane+time taken by bus

=
`4.14h+0.5h=4.64h`

Hence, option (C) is correct.
