Question

Two planes travel at a constant speed which plane a travels 2000 and 800 miles in five hours Plan B travels 3885 miles in seven hours which plane is faster

Answer 1

Since its speed is higher, plane 1 is faster than plane 2.

Explanation:

Comparing Speeds

The formula for the speed of an object who travels a distance d in a time t is:

`\displaystyle v=(d)/(t)`

We have to compare the speeds of the two planes:

The first plane travels d1=2800 miles in t1=5 hours

The second plane travels d2=3885 miles in t2= 7 hours

Calculate both speeds as follows:

`\displaystyle v_1=(d_1)/(t_1)`

`\displaystyle v_1=(2800)/(5)`

`v_1=560\ mi/h`

`\displaystyle v_2=(d_2)/(t_2)`

`\displaystyle v_2=(3885)/(7)`

`v_2=555\ mi/h`

Since its speed is higher, plane 1 is faster than plane 2.
