Answer 1

Answer:

50 km/hr

Step-by-step explanation:

Given that she can reach her office in 2 hours by travelling with speed of 75 km/hr .

Here,we have time,speed so we get distance from these.

Formula : Speed = (distance)/time

=> Distance = ( speed )( time )

=> Distance = 75(2)

=> Distance = 150 km

Therefore, Distance = 150 km

But she reached her office with 1 hr late

so time taken = 2+1

=> time taken = 3 hrs

Now we have Time = 3 hrs, Distance = 150km

Using formula Speed = Distance/time

=> speed = 150/3

=> speed = 50 km/hr

Speed that she travelled by late 1hr is 50 km/h.
