Question

a bus travells 400KM with an average speed of 40kmph . how much time it takes to cover the distance type by sum who does the right one I'm going to mark brain list purple you​

Answer 1

Answer:

The formula which relates distance d, time t, and speed or rate of travel r is:

d = rt.

We're given that the traveled distance d = 400 km and an average speed, r = 80 km/hr.

Substituting into the distance-rate-time formula for d and r to find the time t traveled , we get:

d = rt

400 km = (80 km/hr)t

Now, dividing both sides by 80 km/hr, we have:

(400 km)/(80 km/hr) = [(80 km/hr)t]/(80 km/hr)

[(400 km)/(80 km)]hr = [(80 km/hr)/(80 km/hr)]t

5 hr = [1]t

t = 5 hr is how long a trip will take in hours if you travel 400 km at an average speed of 80 km/hr.
