Question

a bus is moving at a speed of 84 km/hr how much distance will it cover in 1minutes 45seconds

Answer 1

hey there !!!

speed of bus = 84km/hr.

and time = 1min. 45 sec. means 60+45 = 105 seconds.

now ,

distance = speed × time

firstly we find speed in m/sec. so , 84km/hr by converting into m/sec .
we get 84 × 5/18 = 23.33 m/sec.

now ,

distance = speed × time

distance = 23.33 × 105 = 2450m

now ,

converting it into km .

we get 2450/1000 = 2.45km

hence the bus will cover up 2.45km in 1 min. 45 seconds.

hope it helps !!

Answer 2

HERE IS THE ANSWER OF YOUR QUESTION :-

___________________________

Given :-

Speed of bus in km/hr = 84 km/hr

Speed of bus in m/s = 84 x 5/18 = 23.333 m/s

Time = 1 min 45 sec

We know that,

1 min = 60 sec.

So, Time = 45 + 60 = 150 sec

Distance =?

Distance = speed x time

distance = 23.333 x 150
= 2449.9 m

Distance covered by bus in km = 2449.9/1000
= 2.449

On rounding off we get,.

distance = 2.45 km
