Question

A bus is moving at a speed of 84 km/hr. How much distance will it cover in 1min 45 sec?

Answer 1

Speed =Distance /time

time =1min45 sec

60+45

= 105sec

So, 84=d/105

d = 84*105

=8820km

Answer 2

Hello!

Step 1. Converting Speed into its SI unit i.e km/hr to m/sec.

     Speed=84*(5/18)=24.33 m/sec

Step 2. Converting Time into its SI unit i.e min to sec.

     Since, 1 min=60 sec

     Therefore, Time= 60+45 sec or 105 sec.

Step 3. Using formula, Distance = Speed X Time i.e 24.33 X 105 by above calculations. We get 2450 m.

Step 4 (Optional). If you want to get the answer in km/hr. Simply divide the answer by 1000 i.e 2450/1000 = 2.45km.

Hence, The distance covered by the bus under the given condition is measured to be 2.45 km or 2450 m.

Good Luck!
