Answer:

2 hrs

Step-by-step explanation:

The formula for speed is given as:

v=\frac{d}{t}\\\\t=vd

Let X be the speed of plane B. Given that the time to cover there respective distance is equal, we can equate as below:

Time=\frac{Distance }{Speed}\\\\\frac{750}{x}=\frac{900}{x+75}\\\\750(x+75)=900x\\\\\\x=375\ mph

Plane A's time is therefore calculated as:

Time=\frac{Distance}{Speed}\\\\=\frac{750}{375}\\\\=2\ hrs

Hence, it takes A 2 hrs to travel 750 miles.

Viktor [21]

Answer:

$1632

Step-by-step explanation:

Given data

Principal= $1200

Rate= 12%

Time= 3 years

The simple interest expression is given as

A= P(1+rt)

substitute

A=1200(1+0.12*3)

A=1200(1+0.36)

A=1200*1.36

A=$1632

Hence the amount is $1632
