Question

a Bus is moving at a speed of 84 k.m./hr . How much distance will it Cover in 1min. 45 second. please give me solution.. and answer is.. 2k.m. 400mearer

Answer 1

Speed=84km/h
Time=1min 45sec
=60 + 45 sec
=105sec

First convert km/h to m/s
84*1000/3600
84*5/18
42*5/9
14*5/3
70/3 m/s

Speed= Distance/Time
Distance= Speed * Time
= 70/3 * 105
= 70 * 35
= 2450 m

Convert m to km
2450m= 2450/1000
= 2.450km

There is a variation in answer because of the possibility that the speed may be taken in decimal not in fractions as I have done.
