Question

starting from 1.4 miles away a car drives towards a speed check point and then passes it the car travels at a constant rate of 52 miles per hour the distance of the car from the check point is given by d=1.4-52t at what times is the car 0.6 miles from the check point

Answer 1

Answer: At t=0.015 hours when the car 0.6 miles from the check point.

Explanation:

Since we have given that

Distance traveled by him towards a speed check point = 1.4 miles

Speed at which he is travelling = 52 miles per hour

Let the time taken by him be x

Since we have the equation

`d=1.4-52t`

where d denotes distance

and t denotes time.

If we have given that the car 0.6 miles from the check point.

So, we put the value of d in place of it .

`0.6=1.4-52t\\\\0.6-1.4=-52t\\\\-0.8=-52t\\\\0.8=52t\\\\(0.8)/(52)=t\\\\0.015=t`

So, at t=0.015 hours when the car 0.6 miles from the check point.
