Question

I keep getting the wrong answer​

Answer 1

Answer:
`f(t)=550t`

Explanation:

Given

Distance between Toronto to Dallas is 1200 miles

speed of the plane is 550 mph

We know,
`distance=speed*time`

for any time t, distance is given by

`distance=f(t)=550* t`

where t is hours

for
`t=0,f(t)=0` i.e. plane is at Dallas at 2 pm

time taken to reach dallas is
`(1200)/(550)=2.18\ \text{hr}`
