Question

You are driving to visit a friend in another state who lives 440 miles away. you are driving 55 miles per hour and have already driven 275 miles. choose and solve the equation showing how much longer, in hours, you must drive to reach your destination.

Answer 1

Time for the whole journey;
Time=
`(Distance)/(Speed)`
t=
`(440)/(55) hours`
t= 8 hrs
In driving 275 miles, you take,
t=Distance/speed
t=
`(275)/(55)`
t= 5 hours
The remaining traveling time is;
8-5
= 3 hours
