Answer:

2 hours 30 minutes

Step-by-step explanation:

Speed = Distance/Time

Time = Distance/Speed

The car covers 60Km in 1 hour 30 minutes i.e. 90 minutes:

Speed = 60Km*60/90 mins

= 40km/hr

To cover 100 km at the same speed, i.e.:

Time = 100Km/40km/hr

= 2.5 hrs

= 2 hours 30 minutes

Write an equation of the line that passes through (1,2) and is parallel to the line y=-5x+4
valentinak56 [21]

Answer:

The equation of the Parallel line to the given line is  5x+y-7=0

Step-by-step explanation:

<u><em>Explanation:-</em></u>

Given that the line y = - 5x+4 and point (1,2)

The equation of the Parallel line to the given line is  ax+by+k=0

Given straight line  5x + y -4 =0

The equation of the Parallel line to the given line is  5x+y+k=0

This line passes through the point (1,2)

             5x+y+k=0

            5(1)+2+k=0

⇒              7+k=0

                   k =-7

<u>Final answer:-</u>

The equation of the Parallel line to the given line is  5x+y-7=0
